As a result of gradual degradation in the inhospitable environment of the oil industry and frequent handling, irreparable damage occurs to each cable harness. Therefore, a customer from Tashkent approached us with a request for the production of cable harnesses that can be placed in an already operating mining system. It will go through a total overhaul process and the new TENEO cable harnesses will significantly extend its life. The entire solution was custom made from scratch. After obtaining the basic needs of the customer and clarifying the input technical parameters, we prepared a complete project including a combination of suitable wires, steel handles and connectors.

Because the bundles connect the most distant devices at the top of the tower (Top Drive), extreme lengths of cabling were required. It has a length exceeding 1.5 kilometres, of which 580 meters are only for the power cable harness. The length is also reflected in the weight attacking 1.6 tons in the case of a powerful power cable harness. The weight of TENEO drilling rig cable harnesses is not only determined by their length, but also demonstrates the robustness of the design.

TENEO harnesses and EX connectors resist not only aggressive oil industy chemicals, but also withstand harsh mechanical handling. For example, the harnesses must withstand being run over by heavy trucks and cargo vehicles while maintaining their spark-proof features and resistance to electromagnetic interference. We implemented antistatic shielding using 900 meters of special braid manually wound on the cable.

We finished the cables with a combination of industrial connectors of the TENEO TEX - TENEO TSL series for the control cable harnesses and TENEO TEX - TENEO TNR series in the case of the power harness. Thanks to the use of ATEX/iECEX certified TEX connectors, both types of TENEO cable harnesses are fully spark-proof, exceeding the requirements of international standards and compatible with established Amphenol and Winchester standards. The power cable harness can safely transmit currents of up to 1 000 A. The control harness consists of 4 cables that contain up to 50 individual wires.

To attach both types of harnesses to the construction of the mining set, we designed and made special flanges from stainless steel. The customer simply places these 50 kg giant handles into the current structure of the oil tower and thus secures the bundles in place. With no need for any modifications.

The entire solution for a customer from Uzbekistan belongs to our custom-made projects. We sucesfully aim to solve any interconnection need in countless industrial fields.

TENEO circular connectors are not only the result of machining. We use a number of modern and time-proven technologies to manufacture individual connector components.

One example is the production of insulators for VS / VSG / VST connectors. We manufacture the insulators of the VS line connectors using the method of plastic pressing and thermoforming. A suitable loose granulate is heated and pressed into a mold to create a solid mechanically and temperature-resistant connector insulator in a precise shape requiring minimal post-production retouching. The insulator thus fits precisely into the metal body of the VS connector and thus ensures maximum resistance and tightness when used in hermetic installations.

Unshielded multi-pole VS connectors are designed for use in control, automation and telecommunications technology, stationery and mobile devices, signaling and remote control applications, as well as in heavy industry. A threaded coupling nuts with the possibility of sealing is used for the connection. The design of the connector allows connecting and disconnecting the circuit under voltage (but not under current load), and this with all poles of the connector simultaneously. For example VS series connectors are used for connecting flight instruments in Czech and Polish aircraft & drones, both military and civil. They are popular for their robustness and increased climate resistance.

Between April 17th and 21st, we will be happy to meet you at the international fair in Hanover, Lower Saxony. You will find our exhibition in hall 12, position F83.

The six-page brochure contains the entire range of our circular connectors - from miniature ones (e.g. VS connectors) to high-voltage ones. The goal was to simply and understandably display each series of connectors and thus enable the customer to quickly find their way around and make an easy choice. The electrical and mechanical properties of the individual series are presented in an abbreviated form in the brochure. Our catalogs continue to serve for a detailed overview of a specific series.

VS connectors, BS connectors and SR, RM and RWN connectors are designed for installations where stable transmission of control and auxiliary signals is required. The TEX and ZGT series represent highly resistant solutions for the explosive environment of the mining industry (iECEx, ATEx). TSL connectors, MOG connectors and TNR connectors will find application not only in the mining industry, but also in transport technology.

A brochure containing not only VS series connectors can be downloaded in PDF format at this link. If you need a printed version, please contact our product manager at the e-mail address m.rehor@teneo.cz

We are not just a classic serial manufacturer of products from catalog pages. We can flexibly deliver an unique custom made solution. And such a solution does not even have to consist for the most part of our products. The latest such example is the express production of 18 different cable harnesses containing automotive connectors of different brands.

We developed and manufactured these cable harnesses according to the customer's basic drawings. We ourselves enriched the assignment with experience from already implemented advanced solutions for transport and mining technology. After full agreement on the project, production took only three days.

The harnesses in the truck connect the peripherals (eg servomotors, lighting, horn) and the control unit. They consist of AUX connectors for voltage up to 25 V and connectors for data transmission. In total, the harness consists of five to ten multi-pole connectors. Although maximum resistance was not a priority, our solution fulfills and exceeds the specification. Harnesses can withstand mechanical stress (joint movement, trampling down) and climatic influences.

Do you want to develop an unique connection solution for your project, or supply cable harnesses tailored to your established equipment? Thanks to our own development team, universal production and many years of experience in various industrial fields, we will quickly find a solution for you too!

Michal graduated from the prestigious Faculty of Electrical Engineering at the Czech Technical University (ČVUT), majoring in Electrical Engineering, Energy and Management. During his studies, he gained valuable experience on projects related to electrical installation in the harsh conditions of nuclear power plants.

He wants to use this type of practical knowledge during his work in TENEO. An overview of the project documentation and the ability to accurately process technical requirements will help him to participate in the development of advanced solutions - for example, industrial products intended for explosion risk atmospheres containing Methane.

He will also aim to raise awareness of the new connector series designed for the mining industry and to find their use in other segments as well. Michal takes as a challenge the launch of sales of EV charging stations, which TENEO distributes in the Czech Republic in cooperation with the Spanish holding SIMON ELECTRIC. Due to his interest in electromobility and green energy, he looks forward to this task.

In his free time, Michal enjoys mountain biking, travels around Europe by bike with friends, skis and flies an ultralight plane.

3D printing is nothing new here. However, the use of this particular world-awarded 3D printer is a significant step towards even higher quality and speed of creating individual components and entire product prototypes.

The printed model is used for physical evaluation of the product and demonstrates to the customer the functionality of the solution designed by us. Compared to conventional production, 3D printing is many times faster and cheaper. Thanks to this, we can present technical proposals as soon as possible after the assignment, present more variants (still in the project phase) and do not have to interfere with the plans for series production. This precisely tailored "product preview" is another part of our philosophy, which relies on flexibility and the speed of customized customer solutions development.

3D printing technology is useful in-house as well. With high-quality PLA and PETG printing plates, we print technological components that facilitate production, spare parts for our machines and improvers for production units.

What we are, we are also thanks to the awareness of the importance of following new trends and technologies.

The mighty TENEO power cable harness will serve for the safe transmission of high voltage between the terrestrial electrical switchboard and the top of the drilling rig. In a potentially explosive atmosphere, the 690 V distribution is ensured not only by the durable braiding of the cabling, but also by the spark-proof connectors of the TENEO TEX series, which in all respects exceed the requirements of ATEX certification.

The harness consists of three separate electrical phases and one ground conductor. For a trouble-free placement in the construction of the drilling set, we designed a 46-meter-long bundle: the initial 8 meters of the cable harness are branched into three separate conductors for easy connection to the switchboard, the last meter then forms the end for connecting appliances at the top of the tower. For the final segment, we tailor-made massive stainless steel handles that simply fit into the existing load-bearing structure.

Because it is an installation in a hazardous environment in the mining industry, we have connected TENEO TEX single-pin connectors to both ends of the cable harness. They can transmit up to 990 A / 1,000 V and thus exceed customer requirements by almost 40%. Their spark-resistant construction and fully hermetically sealed connection to the conductor make the TENEO TEX series an ideal solution for gaseous atmospheres with a risk of explosion and for installations with the need for compatibility with established Amphenol or Winchester products.

This cable harness is further proof of our ability to efficiently produce tailor-made solutions that are not only quickly available to the customer, but also cost-effective.

You can see photos from the cable harness assembly in the gallery. A time-lapse video from the final stage of packing and preparing the expedition is below.

Custom made cable harness TENEO TEX AUX newly provides Power supply of auxiliary equipment of the drilling set of the company MND Drilling & Services a.s.. Due to its location in the epicenter of an explosive gas atmosphere, our solution exceeds the requirements of ATEX certification and thus conducts energy in each of the 19 conductors safely and in all conditions.

This is mainly due to the use of TENEO TEX series connectors. We have fine-tuned their construction for the specific needs of the mining industry. However, not only the connector itself is spark-proof. We also solve fully hermetically the connection of the connector to the cable. Long time developed TENEO potting compound uncompromisingly seals the joint and withstands extreme environmental conditions.

In addition, we have designed special stainless steel handles for this 225 kg giant. With this customization, we ensured a trouble-free attachment of the TENEO cable harness to the already existing Bentec hinges without the need for additional costs for the modification of the supporting structure.

We are pleased to be able to customers such as MND Drilling & Services a.s. provide comprehensive tailor-made solutions - everything from design and project, through construction, own production, assembly to international guarantees.
