The GTG-VK2 is an effective solution from GORELTEX for connecting power and inserting cables under thermal insulation in electric heating systems. It simplifies installation and prevents damage to the heating cable when inserting it under thermal insulation. It also allows for splicing heating cable sections for T-shaped branches. The GTG-VK2 is suitable for all types of GTG heating fittings and third-party cables.

The OKT-2 support brackets are designed to easily attach to round pipes. The box is secured to the pipe using a metal cluminaire included in the delivery kit. The cluminaire ensures ground integrity between the pipe and the box body.

Explosion-proof GTG-VK2 boxes allow connection of up to three heating cables and temperature sensor cables. Seal type must be specified upon order.

Upon customer request, multiple OKT-2 support brackets can be installed on the enclosure to connect more than three heating elements, and the terminal block arrangement inside the box can be changed. The devices are manufactured with varying OKT-2 support bracket heights (H) below the thermal insulation thickness, ensuring a sealed thermal insulation and eliminating the risk of cable damage at the termination points. The mechanical strength of the GTG-VK2 significantly exceeds that of standard DESTU polyester thermal insulation entry and feedthrough devices, allowing operation at temperatures down to -75°C (high-quality DESTU devices down to -40°C, while budget-friendly devices can only operate down to -20°C). They support the connection of flat heating cables up to 17 mm wide.

Scope: explosion-hazardous areas of premises and outdoor installations according to explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996) and areas dangerous for ignition of combustible dust, according to GOST IEC 61241-3-2011, hazardous industrial facilities of I, II, III, IV hazard classes, supervised by Rostekhnadzor of the Russian Federation and national technical supervision agencies of the CU and CIS countries.

The mechanical strength and impact resistance of OKT-2 support brackets significantly exceeds their polyester counterparts, many of which break at temperatures as low as -20°C, even under light loads.
