Insulate Heat Shrinkable Seleeves

Product Description

Functions:

The heat-shrink materials are obtained by cross-linking of polyethylene with chemical or radiation method. The shape of a product is formed at high temperatures and then solidified by cooling it to a room temperature. The product highly increases its cross dimensions during this process. By heating the product to temperature 120/200 during assembling we cause its form to be melted and, owing its "shape memory", it will attempt to return to its original shape, thus significantly decreasing its cross dimensions and tightly closing the object placed previously into it. This ensures electrical insulation, anticorrosion protection, improves aesthetics. The cross-linked polyethylene is highly resistant to stress corrosion, solvents, acid and base solutions, salts, petrol and oils. Certain products are covered inside with a glue that additionally increases their tightness and pressure resistance. They are used for insulating of terminals, joints, clamps, holders, bus-bars, wire bundle connecting and protection of various elements in electrical and electronic engineering as well as machinery. The longitudinal dimensions of the heat-shrink products increase (e. G. Joints) or decrease (e. G. Sleeves), which has been defined in the description of the individual groups of the products.

Specification and kinds:

1) heat shrinkable anti tracking tubing

2) thin wall heat shrinkable tubing. Standard colour: Red, black, yellow, blue, green

3) 10kv and 35kv bus bar antiflaming insulation heat shrinkable sleeve. As the insulation of busbars in switchboards. The tubes enable to decrease the distances between phase busbars-and at the same the switchboard overall dimensions, protect from corrosion, help to avoid accidental short-circuits, increase personnel work safety.

4) heat shrinkable stress controlling tube. Standard colour: Black

5) heat shrinkable insulation tube, standard colour: Red and black
6) heat shrinkable end cap: Its used for sealing and protecting the ends of power and telecommunication cables having metal or plastic coats. The caps are inside coated with hot melt adhesive. Shrinking must be started from the blind end.

7) heat-shrink distribution joints (breakouts): Its applicated to branch jointfor 1kv to 35kv power cables. And the body is made of cross linked polyethylene, inner surface covered with hot-melt glue.

8) heat-shrink closures: The closures are made of cross linked polyethylene. The inner surface is covered with a hot-melt glue. The outer surface is covered with dots of a green dye which changes its colour into black when a suitable shrinking temperature is reached. The locking rail is made of a spring stainless steel. Its application sealing single cable cores, branches and joints in power engineering and telecommunication.
