Application

This cable is designated for industrial blasting operations under the temperature from 60C below zero till 50C above zero, for short-term running under the voltage 0,38 kV and instant running under the alternating voltage till 0.55 kV or direct voltage 1.5 kV.

The wires running is admitted under the instant direct voltage till 3.0 kV.

 

Construction

Cable leads
Annealed copper wire of 0.5 or 0.8 mm in diameter (single-wired); 0.7 mm in diameter (double-wired)

Insulation
Colorful polyethylene, thickness 0.35 and 0.6 mm accordingly to the cable lead diameter.

Technical characteristics

Wires with cable lead diameter 0.5 mm are applied as electric spark igniters outputs; with diameter 0.7 and 0.8 mm — for toll circuits.

Cable leads electric resistance to direct current, counted in the temperature 20C and length 1 km, not more:

  • 36 ohm — for wire with cable lead diameter 0.8 mm
  • 50 ohm — for wire with cable lead diameter 0.7 mm
  • 93 ohm — for wire with cable lead diameter 0.5 mm

Wires with cable lead diameter 0.5 mm supplies by length not less than 1500 m;

With cable lead 0.7 and 0.88 mm not less 500 m.

It is admitted to pass scanty stretch not less than 100 m in their quantity and not more than 10% from the delivered lot.

Warranty period is 1 year since its manufacture.
