Explosion-proof equipment plant
OKT4 support bracket is intended for insertion of heating cable under the layer of thermal insulation.
The bracket may be used either as part of GTG-VK2 boxes intended for electrical connection to the cable, or it may be supplied separately.
Rounded edges exclude damage of heating cable during mounting. The product is mounted to the conduit by means of two metal rings that ensure ground circuit continuity.
OKT4 is made from aluminum alloy and that is why it became possible to reduce its size twice compared with previous analogues made from nickel-plated brass. Moreover, aluminum is resistant to impact loads. The bracket may be operated under negative temperatures up to -60 degrees.
Operating experience of the previous product and customer‘s requests were taken into account when designing support bracket OKT04. Upon customer‘s request, more than one bracket may be installed on the terminal box.
Scope of application – outdoor and indoor hazardous areas as per explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996), areas with presence of combustible dust, as per GOST IEC 61241-3-2011, dangerous production facilities of I, II, III, IV hazard class supervised by Rostechnadzor of the RF and national technical supervision bodies of the Customs Union and CIS countries.
