FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What is the difference between TGSH and TGSH2G?
Both cables combine a vulcanised textile reinforcement braid (TG = Textilgeflecht) with non-metallic semi-conductive elastomeric core screens (SH = Schirm aus halbleitendem Elastomer). TGSH uses standard +90 °C 3GI3 EPR insulation, while TGSH2G upgrades the insulation to a high-temperature 2G elastomer compound for higher current density on ultra-high-power longwall shearers.
Why do longwall coal operators prefer SH elastomeric screens over braided copper wire screens?
Inside a longwall Bretby cable handler, the cable bends back and forth thousands of times under tension. Metallic screen wires eventually suffer fatigue fracture, and broken wire ends pierce the phase insulation. The SH conductive rubber screen contains no thin wires to snap while maintaining full earth-leakage protection via the bare interstitial earth conductors.
What voltage ratings are covered by the TGSH / TGSH2G series?
TGSH and TGSH2G are manufactured for 0.6/1 kV (1000 V / 1140 V), 1.8/3 kV (3.3 kV longwall systems), and 3.6/6 kV (see also (N)TS-TGSH 3.6-6 kV) to cover all standard underground longwall shearer voltage levels. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and sheath dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
How does the TG textile braid improve cable service life on the coal face?
Vulcanised between the inner and outer 5GM5 polychloroprene sheaths, the high-tenacity TG textile braid locks the two rubber layers into a single composite shell that resists longitudinal ripping, Bretby link pinching, and torsional twisting. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and sheath dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
