Cables mine and excavator, KGPE

Design elements:
The conducting vein twisted from copper or copper tinned a provolok (class 5);
Semiconducting screens from electroconductive rubber of the RE-2 type;
Isolation of the main veins from rubber like RTI-1 on the basis of natural and butadiene rubber;
Grounding vein;
Auxiliary vein with isolation from propylene block copolymer with ethylene;
Winding from a polietilentereftalatny film of the PET-E brand;
Internal cover from rubber on the basis of isoprene and butadiene rubbers;
External cover from rubber of the RSh-1 type (for a cable in tropical execution - RShN-1).

Note: Application as material of isolation of an auxiliary vein of block copolymer of propylene with ethylene ensures its high safety at repeated bends of a cable that prolongs the term of its operation. At the request of the consumer the cable can be made in a cover of bright color.

Scope:

Cables of the KGPE brand are intended for connection of excavators and other mobile cars or electroinstallations to electric networks on rated voltage to 6 kV of alternating current with a frequency of 50 Hz on the main veins and to 380 V on an auxiliary vein.

Cables are intended for operation in the open air. Are mainly applied to excavators and other mobile mechanisms equipped with the equipment of automatic shutdown at single-phase short circuit on the earth. Isolation of cables is steady against influence of ozone within 3 hours at concentration of 0,0015%. Cables in tropical execution of a rack to defeat by mold mushrooms.

Service life of cables - not less than 3 years.
