KNS 2P

Description

This manual applies to KNS self-regulating heating cables (hereinafter referred to as cables) designed for use in electric heating systems for pipelines, reservoirs, systems and roofs of residential, industrial, and administrative buildings.

The cable automatically adjusts its heat output depending on changes in the surface temperature of the object.

The cable can be cut at any point for the convenience of its installation characteristics. The minimum length of the cut section should be at least 0.2 m.

The same length of cable can pass through areas with different surface temperatures of the object.

Heating sections' ends are covered with a braid for practicality.

Explosion safety is ensured:

• implementation of the stabilization structure
• the presence of an electrically conductive shell (screen) providing connection to deceleration systems to create a reliable deceleration network
• selecting sheath materials with maximum electric resistance on the cable surface, measured according to clause 26.13 GOST 31610.0 not exceeding 10^4 ohm at temperature (23±2) °C and relative humidity (50±5)%

DESIGN AND WORKING PRINCIPLE

Design

The heating cable consists of the following elements:

• copper stranded conductive wires;
• heat-emitting element (self-regulating semiconductor matrix) with a positive temperature coefficient;
• thermal insulation
• electrical insulation;
• protective sheath (braid made of copper stranded wire).

Working Principle

Heating occurs due to the passage of electric current through the self-regulating semiconductor matrix from one conductive wire to another. The matrix has a positive tempera

ture coefficient of resistance, meaning the higher the cable temperature, the less energy is emitted by
