APPLICATIONS

HTKSH  and HTKSHekw  halogen free cables are intended for interconnections between switching and transmission equipment, for analogue or digital data transmission in industrial electronics and control applications all in objects of sharp fire protection requirements, particularly in fire alarm and fire automatic control systems.

The cables are certified by Scientific and Research Centre for Fire Protection - National Research Institute (Centrum Naukowo-Badawcze Ochrony Przeciwpożarowej - PIB) at Józefów.

Halogen free cables are applied in locations where, in case of fire, higher safety for human beings and expensive electronic equipment is required. The cables are flame retardant and their smoke emission is low, emitted fumes are non toxic and non corrosive.

Cable circuits are protected by an overall electrostatic shield (ekw) against external electric field interferences.

The cables are suitable for fixed indoor installations.

CONSTRUCTION                                                                                                           

–  bare annealed copper single wire round conductors,

–  halogen free compound insulation - colours in accordance with PN-92/T-90321 standard,

–  insulated conductors twisted into pairs,

–  pairs laid-up into a cable core,

–  cable core wrapped in a polyester tape,

–  HTKSHekw  - overall electrostatic shield incorporating a plastic laminated metal foil and a tinned copper drain wire,

–  red cable sheath made of halogen free compound type HM2 according to EN 50290-2-27 and VDE 0250‑214 standard.
