Wires with copper veins with isolation from polyethylene are intended for industrial explosive works. Wires with a diameter of conducting vein of 0,5 mm are applied as the output ends of electroigniters, with a diameter of 0,7 and 0,8 mm - to the main lines.
Wires are intended for short-term operation at a voltage of 380B and instant - at an alternating voltage of 660 V or constant 1500 Century.
Operation of wires is allowed at an instant constant tension till 3000 Century.
VP brand wires - wires with copper veins with polyethylene isolation for explosive works.
VP-T - the wires with copper veins with polyethylene isolation for explosive works intended for operation in areas with tropical climate.
Number of veins in a wire, nominal diameters them, the nominal thickness of polyethylene isolation, the maximum outer diameters of wires have to correspond specified in the table:
|Number of veins||Nominal diameter of a vein||Nominal thickness of isolation||Maximum outer diameter||Settlement weight is 1 km of a wire, 1 kg|
Conducting vein - a copper wire;
Isolation - the polyethylene painted in various colors. Color of isolation of a two-core wire has to be various. Isolation of wires has to be cold-resistant. Wires of the VP-T brand have to be mold mushrooms, resistant to defeat;
Twist - veins are twisted with a step no more than 20 diameters on twist. In coordination with the consumer production of the two-core not twisted wire is allowed.
The electric resistance of conducting veins to a direct current counted for temperature 200C and length of 1 km, has to be:
No more than 93 Ohms for a wire with a diameter of vein of 0,5 mm;
No more than 36 Ohms for a wire with a diameter of vein of 0,8 mm;
No more than 50 Ohms for a wire with a diameter of vein of 0,7 mm;
Construction length has to be:
Not less than 1500 m for a wire diameter of a vein 0,5mm;
Not less than 500 m for a wire with a diameter of vein of 0,7 and 0,8 mm.
Warranty period - one year from the date of operation.
