Description

Novel silica gel cold-shrink tube

Technical Field

The utility model relates to a shrinkage pipe technical field specifically is a novel silica gel shrinkage pipe.

Background

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. Early cold shrinkable cable terminations used silicone rubber cold shrink components for additional insulation, and the electric field treatment still used a stress cone type or stress band wrapped. It is now common to use cold shrink stress control tubes with voltage ratings from 10kv to 35 kv. The cold contraction cable joint adopts a cold contraction insulating tube as reinforced insulation at a level of 1kv, adopts a joint cold contraction insulating part with an inner semi-conductive shielding layer and an outer semi-conductive shielding layer at a level of 10kv, and adopts a cold contraction branch sleeve at a branch position of a three-core cable terminal. The cold-shrinkable cable accessory has the advantages of small volume, convenient and rapid operation, no need of special tools, wide application range, less product specification and the like. Compared with the thermal contraction type cable accessory, the thermal contraction type cable accessory does not need fire for heating, and the thermal contraction type cable accessory can not be moved or bent after being installed, so that the internal layers of the accessory are not separated. At present a lot of cold reducing pipes when using need pass the cold reducing pipe with the cable, take out inside support and reach the guard action that contracts, but a lot of times, when penetrating the cable inside, when using on longer cable, it is very inconvenient to take out the line, and the shrinkage pipe length uses easily for a long time and leads to the pipe fracture of shrinking, has consequently designed a novel silica gel cold reducing pipe.
