Application fit

Is FLAME ARREST LT right for your machine?

Specify FLAME ARREST LT where high-temperature cables are simultaneously exposed to cutting fluids, hydraulic oil, quench water, or steam that would wick into open glass-braided cables.

Furnace, kiln & high-temp zone

Suitable

Withstands +250 °C continuous ambient heat and +350 °C radiant splash around continuous casters, quench tanks, and die-casting machines.

Immersion & wet locations

Suitable

Continuous extruded outer jacket over the internal E-glass braid blocks wicking of quench water, glycol, steam, and caustic washdown.

Fixed installation

Suitable

Seals cleanly inside standard liquid-tight compression cable glands (IP67 / IP68) unlike porous outer fibreglass braids.

Motorised monospiral reel

Not suitable

Designed for fixed and flexing machine drops in wet hot zones; use NSHTÖU or RXP for heavy crane drum reeling.

FAQ

Questions engineers ask first

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

Why do standard fibreglass-braided high-temperature cables fail in steelmill run-out tables and die-casting cells?
Exposed outer E-glass or ceramic braids act like a lamp wick when splashed with water-glycol hydraulic fluid, cutting oils, or quench steam. The wicked fluid carbonises inside the cable under heat and causes phase-to-phase tracking. FLAME ARREST LT places a continuous extruded elastomer jacket outside the reinforcing glass braid to block fluid ingress completely.
Can FLAME ARREST LT be sealed in standard IP68 compression cable glands?
Yes. Because the outer surface is a smooth, concentric extruded elastomer rather than a woven textile braid, standard nickel-plated brass or stainless-steel compression glands achieve a full IP67/IP68 liquid-tight seal at junction boxes.
What retains mechanical cut-through strength if the outer layer is an elastomer?
Beneath the extruded liquid-tight outer sheath sits a high-tensile braided E-glass reinforcement layer over a PTFE barrier wrap, giving the cable the crush and cut-through resistance of a glass-braided cable with the fluid seal of a rubber cable.
When should I choose Type MG Multi-Conductor instead of FLAME ARREST LT?
Use FLAME ARREST LT up to +250 °C (+350 °C splash) wherever water, steam, oil, or washdown fluids are present. For dry furnace zones operating continuously between +260 °C and +450 °C, select Type MG Multi-Conductor.
