Transition cable element series RKN-ZK (TP) with threaded jointPURPOSE AND SCOPE OF APPLICATION

Explosion-proof transition cable elements are intended for the connection of flat or round electrical wires or optic cables between two enclosures of the explosion-proof equipment, usually between an Exd-enclosure and input Exe enclosure, or between two Exd enclosures. Actual range of operating temperatures is determined by the applied type of the wires or a cable. More detailed information for certain types is provided upon request. Partition nipple-barriers could be manufactured with hook-up wires (conductor), with coaxial cables (coaxial), with optic cables (optic), with flat wires, with clamping screw (bolted) as per the order.

Upon customer‘s request, stranded gas migration preventing heat-resistant hook-up wires  for partition fittings with completely encapsulated internal space.

Scope of application - hazardous indoor and outdoor areas in accordance with explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996), dangerous production facilities of I, II, III, IV hazard classes under supervision of Rostekhnadzor and national supervisory bodies of the CU and the CIS countries.
