Application

TK39...M is being applied to local telephone network for subscriber lines.
It is laid directly into the ground and cable ducts.
The use of this cable in power purposes is not permitted.

Construction

• Conductor is a soft annealed copper wire of 0.4mm;0.6mm and 0.8mm diameter

• Insulation is of solid PE, type ETI2,according MKS N.CO.195

• Four different coloured insulated conductors are twisted to star quad which is the basic element of this cable.

• Cable core is made of concentric or group twisted star quads.

• Core filling is made of petro-jelly

• Core wrapping is realized with two impregnated paper tapes with orange thread under them as the mark of FKN.

• The sheath of the cable is made of aluminium tape covered on both sides with a layer of ethylene copolymer and black coloured PE sheath type
