Mining flexible cables

TU U 31.3-31850229-020:2006
IEC 60502-1 (1998-11)

 

Application

KGVSH () 60 V

Mining flexible cables are intended for operating with spark - proof control devices for AC voltage 60 V and nominal frequency 50 Hz in underground conditions.

Cables are designated for operating at ambient temperature from -30 C to +50 C and relative humidity up to 98 % at 35 C. In conditions of mounting and operating bending: -5 C.

 

Construction

Conductors
Multicore copper stranded round conductors (not less 4 class in accordance with GOST 22483).
Nominal cross-section of conductors: 1.0 – 2.5 mm.

Insulation
Polyvinylchloride (PVC) compound.

Cable core
Polyester thread or PVC-compound based on polyester threads.
Twisted insulated conductors around the cable core.

Oversheath
Polyvinylchloride (PVC) compound (hermetically sealed).

Technical characteristics

Conductors resistance calculated for 1 km at 20C complies:

  • 1.0 mm - 20.4 Ohm;
  • 1.5 mm - 14.5 Ohm;
  • 2.5 mm - 8.8 Ohm.

Insulation resistance of conductors calculated for 1 km at 20 C is at least 10 MOhm.

Cables are flame retardant with a single laying.

Durable permissible conductor temperature must not exceed 70 C.

Cables must resist to tensile force and repetitive bends.

Minimum tolerable bend radius of the cable at installation and operation must equal to min. 10 overall diameters of the cable.

Cables resist destructive effect of lubricating oils.

Guarantee period: 12 months from commissioning date.

Manufactured cable length: not less 150 m.

Service life: not less 5 years.

All products are certified.
