Description
Technical Field
The utility model relates to a terminal cable joint, in particular to shrinkage terminal joint.
Background
The cold-shrink cable terminal is made up by using elastomer material (commonly used silicone rubber and ethylene-propylene rubber) and adopting injection vulcanization moulding in factory, then making it undergo the processes of expanding diameter and lining with plastic spiral support to form various cable accessories. 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.
At present, cold shrinkage stress control tubes are commonly used, and the voltage class is from 10kV to 35 kV. The cold contraction cable terminal adopts a cold contraction insulating tube as reinforced insulation at the level of 1kV, and adopts a joint cold contraction insulating part with an inner semi-conductive shielding layer and an outer semi-conductive shielding layer at the level of 10 kV. The bifurcate part of the three-core cable terminal adopts a cold shrinkage branch sleeve.
The cold-contraction cable terminal 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 risk of the detachment of the internal layers of the accessory (because of the elastic pressing force of the head rest of the cold contraction cable terminal) does not occur when the thermal contraction type cable accessory is moved or bent after being installed. Compared with the prefabricated cable accessory, the internal interface characteristics are ensured by the elastic pressing force, but the prefabricated cable accessory does not correspond to the cable section one by one, and the specifications are more.
The size of a semiconductor part in a conventional cold-shrink terminal is larger, so that the wall thickness of a product is larger, the expansion multiple of the product is smaller, the wire diameter range which can be covered can be correspondingly reduced, and the applicability is lower.
