KNS 2LGG

Description

This passport applies to the KNS self-regulating heating cable (hereinafter referred to as the cable), which is intended for use in heating systems for pipelines, drainage systems, and the roofs of buildings and structures, including at low temperatures, and in potentially explosive environments.

The cable automatically adjusts its heat output depending on changes in the temperature of the surfaces it is applied to.

The cable can be cut to length based on its technical specifications. The minimum length that can be cut is no less than 0.2 m.

The cable should not be overlapped, nor should its conductors be crossed over or overheated at the splice point.

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

The cable is used for both frost protection systems and heating systems, as well as for heating rooms occupied by people.

Explosion safety is ensured:

• Mechanically stabilized construction.
• External grounding coating that ensures connection to grounding systems for the creation of a reliable grounding circuit.

• The insulation material exhibits high mechanical resistance, with surface resistance measurements according to item 26.13 of GOST 31610.0 exceeding 10^4 Ohm when at a temperature of 23°C and a relative humidity of 50%±5%.

COMPLIANCE CERTIFICATES

Self-regulating heating cable for single-core installation.

Self-regulating heating cable brands KNS.

CONSTRUCTION AND PRINCIPLE OF OPERATION

Construction

The heating cable consists of the following elements:

• Copper and tinned conductive wires;
• Heat-generating element (polymer self-regulating material with a positive temperature coefficient);
• Insulation;
• Shielding (casing, braid made of tinned copper wire).
• shell;

Principle of Operation

The resistance varies due to the electric current passing through, allowing the self-regulating matrix to draw energy from one conductive wire to another. The self-regulating matrix, combined with the polymer material and shielded wire of the cable, heats the devices. Consequently, the intensity of heat output changes depending on the temperature indicators of the heating surface (as the surface temperature increases, the heat output decreases).

SAFETY MEASURES

Safety measures for cable installation that are MANDATORY to comply with the warranty conditions:

- Modifications to the cable design are prohibited.

- It is prohibited to apply voltage to the cable while it is still wound on a reel and to preheat the cable on the drum.

- It is prohibited to connect the conductive wires of the cable together to avoid short circuits.

- It is prohibited to operate the cable with parameters that do not match those specified in Table 1 of this passport.

- Welding and work with fire in close proximity to the cable are prohibited to avoid unacceptable external temperature impacts.

- The cable must not be subjected to temperatures above the maximum permissible for its technical specifications according to section 2 of this passport.

- During the installation of the cable line, after completing the installation of the cable ends, it is necessary to check the electrical integrity of the conductors at the joint installation points using a megohmmeter. If the resistance is found to be less than the permissible value during testing, the damaged section of the cable must be removed, and the electrical integrity of the cable conductors must be retested.

TRANSPORTATION, STORAGE, AND DISPOSAL

Transportation and storage of heating cable concerning climatic factors must adhere to the requirements of GOST 15150:

- Heating cables may be transported by all types of covered vehicles. When transporting and handling cargo, the current normative documents must be followed.

- The warranty storage period for the cable is 5 years from the manufacturer.

- The cable should be stored in covered, dry premises with a stacking height of no more than 150 mm.

When storing and transporting the cable, in order to prevent moisture from getting into the conductive sheath and the semiconductive matrix, heat-shrink tubing must be used to ensure airtightness. 

The cables are not environmentally hazardous, and there are no specific requirements for their disposal when they are decommissioned, except for the requirements specified in the relevant documentation for nuclear power plants, for example. Burning the cables in household stoves, burners, or bonfires is not permitted.
