Application fit

Is Type MG Multi-Conductor right for your machine?

Select Type MG Multi-Conductor when multi-core power or control circuits run directly inside +250 °C to +450 °C thermal zones where fluoropolymers (PTFE/PFA) and silicone rubber decompose.

Furnace, kiln & high-temp zone

Suitable

Engineered for continuous +450 °C service on industrial heat-treating furnaces, glass lehrs, ceramic kilns, and plastic extruders.

Fixed installation

Suitable

Cabled multi-core construction simplifies conduit and tray routing compared with pulling multiple loose single-core UL 5170 wires.

Switchgear & control cabinet wiring

Suitable

Colour-tracer coded glass-braided cores permit straightforward phase identification at high-temperature ceramic terminal blocks.

Immersion & wet locations

Not suitable

Fibreglass-braided mica insulation is designed for dry heat zones; for wet, oily, or washdown zones use FLAME ARREST LT.

FAQ

Questions engineers ask first

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

Why does Type MG Multi-Conductor require 27 % nickel-plated copper (ASTM B355 Class 27) instead of 2 % or 10 % nickel plating?
At continuous temperatures of +400 °C to +450 °C, thin 2 % or 10 % nickel coatings allow copper atoms to diffuse through the nickel layer and oxidise rapidly. A heavy 27 % weight nickel cladding (ASTM B355 Class 27) provides a permanent diffusion barrier up to +450 °C.
Is the slight smoke seen during the very first heat-up above +300 °C normal for mica-glass cables?
Yes. The silicone/organic saturant applied to the outer E-glass braid to prevent fraying during cable stripping and pulling volatilises cleanly between +300 °C and +380 °C on initial commissioning, leaving the inorganic phlogopite mica and glass matrix intact for +450 °C service.
How does Type MG Multi-Conductor compare with CERAFIL CN8?
Type MG uses 27 % nickel-plated copper with phlogopite mica and E-glass braid for continuous service up to +450 °C (+550 °C peak). For furnace chambers operating continuously between +500 °C and +1000 °C, select CERAFIL CN8 with pure Nickel 200 conductors and ceramic fibre insulation.
Can Type MG Multi-Conductor be supplied with an outer stainless-steel wire braid?
Yes. For steelmills, foundries, and glassworks where mechanical crushing or molten metal spatter occurs, we supply Type MG with an overall AISI 304 or AISI 316L stainless-steel wire armour braid over the E-glass jacket.
