Description

This flexible heating cable is used in explosive atmospheres to heat electric motors and generators at standstill. It provides reliable protection against corrosion damage and the associated mechanical breakdowns because it effectively prevents condensation from forming, even under extreme conditions.

The heater is supplied ready to connect, which is done via an M20 screwed cable connection fed into an Ex e distributor, or is directly clamped to terminals in an Ex room without a screwed connection.

As these heating cables are self-limiting, overheating is prevented, even if they are laid on top of each other. An additional temperature limiter is not required.

Structure of the heating cable

Copper power conductor wire 1.2 mm?, nickel-plated
Self-limiting plastic heating element
Insulation sleeve made of FEP
Tin-plated copper braiding
Protective sleeve made of FEP
