Application fit

Is TRM-J right for your machine?

TRM-J combines an extruded EI4 rubber inner bedding, a ≥ 90 % coverage tinned copper concentric braid screen and a heavy-duty yellow 5GM3 outer sheath, providing earth-leakage fault protection if crushed or cut in underground mines, quarries and tunnel drives.

Trailing & towing

Suitable

Primary duty: heavy-duty mobile trailing power and control feeders for underground mining drills, loaders, roadheaders and pumps.

Motorised monospiral reel

Suitable

Suitable for slow-to-medium speed horizontal cable reels on mining and quarry equipment up to 15 N/mm².

Festoon & line chain

Suitable

Can be suspended on heavy industrial and tunnel festoon hooks at ≥ 10 × D bending radius.

FAQ

Questions engineers ask first

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

What is the purpose of the concentric tinned copper braid screen in TRM-J?

The ≥ 90 % coverage tinned copper wire braid positioned between the EI4 inner sheath and the yellow 5GM3 outer sheath provides both mechanical protection and an immediate earth-fault current path if the cable is crushed by rockfall or pierced by mobile mining equipment, tripping the earth-leakage relay before phase-to-phase arcing occurs.

What does '-J' mean in TRM-J?

In accordance with DIN VDE 0293, '-J' indicates that the cable includes an insulated green-yellow protective earth core in addition to the overall concentric tinned copper wire braid screen.

Why is TRM-J rated at 0.69/1.15 kV (640/1100 V)?

Underground mining and quarry distribution networks frequently operate at 660 V, 690 V or 1,000/1,100 V AC rather than standard 400 V industrial mains. TRM-J's 3GI3 EPR insulation is rated for 640/1100 V nominal and 690/1150 V (0.69/1.15 kV) continuous maximum operating voltage (Um = 1,270 V).

When should I move from TRM-J to 2XSEYQY or 3GSEYQY?

Use TRM-J for low-voltage mobile mining machinery and pumps up to 1.15 kV. For medium-voltage tunnel boring machines and underground substations at 6/10 kV or 18/30 kV, specify steel-wire-braid armoured 2XSEYQY (6/10 kV) or 3GSEYQY (18/30 kV).
