Features

nnnn

■ Self-limiting

nnnn

Can be used in explosive athmospheres

nnnn

without temperature limiter

nnnn

■ Can be cut to any length due to parallel

nnnn

power circuit configuration

nnnn

■ External protective sheath for resistance to

nnnn

corrosion and chemical influences

nnnn

Tin-coated copper braiding for electrical

nnnn

and mechanical protection

nnnn

■ Easy installation due to high level of

nnnn

flexibility

nnnn

■ Easy on-site cutting and terminating, with

nnnn

silicone cold applied technology even

Description

nnnn

Via two tin-coated stranded copper wires with a

nnnn

cross-section of 1 mm2 each which are positioned

nnnn

In parallel, an irradiated electrically conducting

nnnn

plastic is extruded.

nnnn

This electrically conducting plastic matrix

nnnn

responds to changes of the ambient temperature

nnnn

with a respective increase or decrease of the

nnnn

heating output.

nnnn

Electrical strength as well as protection against

nnnn

humidity and mechanical stress is ensured by two

nnnn

surrounding insulation jackets, whereas the first

nnnn

jacket is permanently bonded to the heating matrix

nnnn

(bonded jacket).

nnnn

Additional electrical and mechanical protection

nnnn

Is achieved by means of the following copper

nnnn

braiding.

nnnn

A flame-retardant, UV-resistive plastic jacket

nnnn

protects the braiding against humidity and offers

nnnn

further protection against major mechanical

nnnn

stress.

nnnn

6. Protective jacket of fluorpolymer

nnnn

or alternatively polyolefin
