Heat shrinkable breakout HBB

Ask Question

Heat-shrink breakout is used for hermitization and filling division core of multicore power cables, organization of cable lines input into the pipe and cable channels.

Application: Heat-shrink breakout is used for hermitization and filling division core of multicore power cables, organization of cable lines input into the pipe and cable channels. For usage in termination and joint cable kits up to 35kV for cables in PVC, paper-oil and PE isolation.

Description: Made from chemically modified PE with adhesive layer. Sealing adhesive layer on the inner side of body and fingers allows to place breakout indoors and outdoors. Hot-melted glue creates adhesion with all widely used polymers and metals, protects from moisture, dust and other contaminations. Breakouts have 2, 3, 4, 5 fingers.

Storage: in clean, dry rooms in the supplier's packaging or in cardboard boxes, at a relative humidity of up to 70%, at temperatures from -10°C to +50°C, avoiding sudden temperature changes and exposure to direct sunlight. The distance to any heating sources should be at least 1 meter (without exceeding the maximum storage temperature). Storage conditions should exclude the influence of aggressive medium: acids, alkalis, fuels and lubricants, solvents, etc.
