Scope
The wire of cathodic protection which is not extending burning holodo-thermo-himo-waterproof PKZNG (A)-HL-T-HS, is intended:
- for stationary installation at the rated alternating voltage of 0,66/1 kV with a frequency up to 1000 Hz or to 3 kV of a direct current;
- for laying in soil of all classes in accordance with GOST 25100 with depth of installation up to 1000 meters;
- for laying on internal surfaces of conduits and technological pipelines with drinking water, technological liquids;
- for laying in sea water at a depth up to 200 meters;
- for laying in the atmosphere of air of types I, II, III, IV on the land and the sea of all macroclimatic areas of execution of V, AHL with installation height to 4300 meters above sea level;
- for laying in explosive zones of open electroinstallations, a zone 2 (V-1g), group of the mix T2 (only for execution of Ex).
Technical specification
The wire is waterproof and resistant to influence of sea, ground, drinking and deep-well water, and also to the diluted solutions of acids and alkalis, oil and oil products, to influence of products of reaction of anode dissolution, including to compounds of chlorine. The wire is steady against repeated assembly bends at a temperature to minus 70 °C inclusive.
The wire consists of a copper vein, isolation and a cover. Isolation and a cover of a wire are made of himo-heatresistant cable polymer of the lowered combustibility. Color of a cover blue or blue, for explosion-proof execution of Ex – black.
