31.3136387500012002
wire one-tendon with a copper tendon with a polyethylene isolation in a polyethylene shell on voltage 380, 660 and 3000 V
CONSTRUCTION
1. CURRENT IS CONDUCTING WIRES copper, corresponds a class 2 for 22483177. Tendons by a section 25 and 35 mm² made from 19 wires.
2. ISOLATION from a polyethylene.
3. SHELL from a polyethylene.
Wires can be made in one-layer isolation-protective shell from light-proof polyethylene, here the nominal thickness of isolating protective shell is equal to the sum of nominal thicknesses of isolation and shell.
APPLICATION DOMAIN
Wires are intended for tacking to the electric networks on nominal voltage 380, 660 and 3000 V alternating current by frequency 50 Hz. for exploitation in the fixed position during the protracted work of water-immersion electric motors in water of artesian mining holes under constraint a 6.86 x 106 Step at an ambient temperature ot minus 40 to 80.
