PURPOSE AND SCOPE OF APPLICATION

GTG-VK1 is an effective solution for connection and input of cables of electric heating systems under hear insulation which simplifies installation and excludes damage to heating cable during its input under heat insulation, as well as it splices ends of the heating cable for T-shaped branches. GTG-VK1 are applied for all types of GTG heating accessories and cables of third party manufacturers. The box shall be fastened to the pipe with two metal fastening clamps which ensure reliability of the grounding circuit between the pipe and the enclosure.

Scope of application – outdoor and indoor hazardous areas as per explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996), for use in presence of combustible dust, as per GOST IEC 61241-3-2011, dangerous production facilities of I, II, III, IV hazard class supervised by Rostechnadzor and national technical supervision bodies of the Customs Union and CIS countries.
