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.

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.
