Mining telephone communications cables: KTPEPKbSHv 60 V

Mining telephone communications cables: KTPEPKbSHv () 60 V

TU U 31.3-31850229-002-2002
IEC 60502-1 (1998-11)

 

Application

Cables are designated for communication arrangement and information transfer in mine networks at nominal voltage of 225 V and 145 V and rated voltage of 375 V and 200 V in outdoor conditions at ambient temperature from -40 to +50 C.

KTPEPKbSHv cables are designated for communication arrangement in mines with laying in horizontal and vertical mining workings and outdoor laying in conditions of hardwiring. Cables resist destructive effect of lubricating oils and diesel oil and mechanical damage.

 

Construction

Conductors
Copper soft wires, diameter 0.7 mm.

Insulation
Polyethylene.

Screen
Aluminum foil; copper wire is under screen.

Inner sheath
Polyethylene.

Covering «KbSHv» type (KTPEKbSHv)
Polyvinylchloride (PVC) cushion under armour;
Armour is made from galvanized steel wires (diameter: 2.0 mm);
Winding by thermally fastened linen;
Polyvinylchloride (PVC) oversheath (oxygen index is min. 27 %).

Cables resistant to high humidity up to 98%, at temperature up to 35 C.

Cables resistant to ambient temperature as follows:

  • up to +50 C;
  • up to -40 C - in conditions of hardwiring;
  • up to -10 C - tolerable bend radius of the cable at installation in conditions of mounting bendings must equal to min. 10 overall diameters of the cable – for KTPEPSHv cables, and to min. 15 overall diameters of the cable – for KTPEBbSHv, KTPEPKbSHv cables.

Cables are flame retardant with a single laying.

Cables resist destructive effect of lubricating oils and diesel oil.

Manufactured cable length: not less 400 m.

Cables can be also laid outdoors, provided they are not exposed to mechanical damages and direct sun.

Guarantee period: 3 years from commissioning date.

The manufacturer can ensure compliance of cable quality with requirements of current technical specification, provided all terms of transportation, storage, installation and use have been observed.

Minimal service life: 5 years from commissioning date.

All products are certified.
