Description

Cold-shrinkable tube with built-in sealing plaster

Technical Field

The utility model relates to a cold shrink tube technical field specifically is built-in sealed daub's cold shrink tube.

Background

Cold shrink tubing is generally referred to as a cold shrink cable accessory. The cold contraction type cable accessory is made up by using elastomer material (commonly used silicone rubber and ethylene-propylene rubber) and making injection vulcanization moulding in factory, then making diameter-expansion and lining with plastic spiral support to form various cable accessory components. When the cable is installed on site, the pre-expansion pieces are sleeved at the tail end or joint of the treated cable, the plastic spiral strip (support) supported inside is drawn out, and the plastic spiral strip is pressed on the cable insulation to form the cable accessory. It is commonly referred to as a cold shrinkable cable accessory because it shrinks under elastic retractive force at room temperature, rather than heat with fire as a heat shrinkable cable accessory.

Common cold shrink pipe is comparatively single on the market, because do not set up corresponding safeguard measure, when using, just the phenomenon of rainwater infiltration can appear to influence the normal use of cable, can burn out the cable even, and then shorten the life of cable, the security performance is lower.
