Heat shrinkable breakouts are designed for insulation, sealing and protection of the root of cable cutting while installing heat shrinkable cable kits. Heat shrinkable breakouts ТПИ are universal and can be applied to any type of multi-conductor cables with plastic, paper oil impregnated and rubber insulated cables, for voltage up to 1 kV.

Cable breakouts are a key element, the "heart" of any heat-shrinkable cable kit. In many ways, it is the quality of the production of heat-shrinkable breakout, which determines the level and status of the manufacturer.

Breakouts are one of the most technologically complex elements in the production. Most of the companies on the Russian market, offering heat shrinkable kits under its own brand, in fact, buy cable breakouts from other manufacturers or use imported components of dubious quality. Against this backdrop, stands “KBT” electrotechnical factory with his full production cycle of all elements of heat shrinkable cable kits.

Cable breakouts ТПИ “KBT” presents a full lineup for the 2-, 3 -, 4- and 5 and 6-cores cables. Color: black. Sizes of  heat shrink “KBT” breakouts before and after shrinkage are designed in such a way, that they coincide with ranges of multi-dimensional heat shrinkable “KBT” kits, spanning 3 successive sections of the cable (e.g., 25-35-50 or 70-95-120 or 150-185-240 mm2)

Cable breakouts ТПИ “KBT” have good insulating quality, high mechanical strength, resistance to ultraviolet radiation, chemicals, corrosive cable oil and weather conditions.

Inner surface of fingers and body of heat-shrinkable breakouts ТПИ has hot melt adhesive layer. After installation, the molten adhesive composition hardens and seals the root of cable cutting.

Cable breakouts prevent moisture from the outside and leakage of the oil composition from the inside of the cable (if the installation of breakout is made for cable with paper insulation).

The layer has excellent adhesion to all materials used in the manufacture of cables, including polymeric sheath cables, the layers of metal screens and armor straps. Protrusion of the adhesive layer after melting guarantees the high quality of sealing.

Packing of all types of “KBT” heat shrink breakouts is unified. Each type and size implemented in sets of 10pcs.
