NSHCGEÖU KON+ST+UL 0.6/1 kV Monitored Tunnel Cable
0.6/1 kV monitored tunnel cable with concentric monitoring, earth conductors, flexible armour and UL certification obtained.
NSHCGEÖU KON+ST+UL is a 0.6/1 kV monitored tunnel cable for mobile coal-cutting and loading machines operating under high mechanical load. The supplied technical specification describes three tinned-copper power cores with 3GI3 EPR and semiconductive rubber insulation, control and monitoring cores, a double concentric arrangement, a GM1b inner sheath, a flexible helix of tinned copper and galvanized steel wires, and a yellow or red 5GM5 elastomer outer sheath. The concentric phase-monitoring screen and overall concentric earth conductor support insulation-fault and damage monitoring when connected to suitable equipment. The source lists 3 kV main-core testing, 2 kV control-core testing, 90 °C conductor operation, 250 °C short-circuit temperature, fixed service from −40 °C to +90 °C and mobile service from −25 °C to +90 °C. UL certification has been obtained, as confirmed for this product; the certificate record and scope should be supplied when required by the project. The page keeps the source configurations together so buyers can request one product while specifying the precise conductor arrangement and monitoring circuit needed for their machine. Confirm the KON/ST/UL core arrangement, monitoring interface, route, termination, mechanical load and final size with TEBAOFLEX.
NSHCGEÖU KON+ST+UL construction
The supplied construction is built around three power cores with double concentric control and monitoring cores. A concentric phase-monitoring screen and overall concentric earth conductor support insulation-fault and damage monitoring when used with suitable equipment.

Applications for NSHCGEÖU KON+ST+UL
The source positions this 0.6/1 kV monitored tunnel cable for mobile machines under very high mechanical load, especially coal-cutting and loading machines in mines. It also lists appliances, devices and auxiliary electrical circuits.
- Mobile coal-cutting and loading machines with the stated monitoring/earth arrangement
- Appliances, devices and auxiliary electrical circuits in demanding mining and tunnel environments
- Installations where a concentric phase-monitoring screen and overall earth conductor are connected to suitable monitoring equipment
- Confirm site classification, monitoring interface, core schedule, termination, S-type changes and mechanical load before ordering
The source provides fixed and mobile temperature windows and a 20 × D S-type distance reference. Apply the project installation drawing and equipment protection requirements to the final selection.
