The GTG-VK1 is an effective solution from GORELTEX Plant LLC for connecting power and inserting cables under thermal insulation for electric heating systems. It simplifies installation and prevents damage to the heating cable when inserting it under thermal insulation. It is also designed for splicing heating cable sections or for creating T-shaped branches. It is used with all types of GTG heating fittings and third-party cables. The box is secured to the pipeline with two metal cluminaires, which ensure ground continuity between the pipeline and the box body.

The OKT-1 support brackets are designed for easy attachment to round pipes. The box allows for the connection of one element of the GTG heating valve. For simultaneous connection of two heating valves, the /2K device version (two input devices or one device for two cables) must be used. The location of the terminal blocks inside the box can be changed at the customer's request for ease of installation. Devices are manufactured with varying heights (H) of the OKT-1 support bracket, below the thickness of the thermal insulation, ensuring sealing of the thermal insulation and eliminating the risk of cable damage at the termination points. Special elastic silicone seals are used for the entry of heating cables. The mechanical strength of the GTG-VK1 design significantly exceeds that of standard DESTU polyester thermal insulation entry and penetration devices, allowing operation at temperatures down to -75°C (high-quality DESTU devices down to -40°C, budget-friendly ones only down to -20°C). They allow the connection of flat heating cables up to 17 mm wide.
