FAQ

Questions engineers ask first

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

What does the 'T' in KGETSh (КГЭТШ) signify compared to KGET (КГЭТ)?

In KGETSh (КГЭТШ), where 'Т' precedes 'Ш' (шахтный = underground mine), 'Т' stands for Тяжелый (heavy-duty mechanical execution) featuring a reinforced double-layer sheath for severe underground coal-face service. In KGET (КГЭТ), the trailing 'Т' stands for Tropical open-pit climate execution. 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 is KGETSh reinforced for heavy-duty longwall shearer service?

KGETSh replaces the single outer jacket of standard KGESh with a vulcanised two-layer polychloroprene sheath reinforced by an open-weave high-tenacity polyamide braid and a crush-absorbing central elastomeric cradle, doubling resistance to rock-fall impact and Bretby trough tearing. 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.

Is KGETSh available for both 1140 V and 3300 V longwall coal faces?

Yes. We manufacture KGETSh in both 660/1140 V (tested at 3.5 kV AC) and 1.9/3.3 kV (tested at 6.5 kV AC) ratings with +90 °C EPR insulation to power modern high-output longwall shearers and roadheaders. 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.

When should I choose KGETSh versus KGEZhTSh?

Choose KGETSh for horizontal or moderately inclined longwall faces and roadheaders requiring maximum jacket tear resistance and tight 5×D–6×D flexibility. Choose KGEZhTSh when steep coal seams or vertical pulls require an integrated galvanized steel wire rope ('Ж') tension element. 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.
