10KV cold-shrinkable cable indoor terminal

Abstract

The invention discloses a 10KV cold-shrinkable cable indoor terminal comprising a cold-shrinkable sheath and a support tube, wherein the support tube is located inside the cold-shrinkable sheath; thetwo ends of the cold-shrinkable sheath are provided with end covers; each end cover comprises a cover wall and a cover surface; the cover wall extends into the support tube; the cover surfaces cover the two end surfaces of the cold-shrinkable sheath; convex rings are disposed on the two ends of the support tube at positions close to the end portions of the cover walls, and have an internal diameter larger than that of other parts of the support tube; ring grooves are disposed on the cold-shrinkable sheath at positions corresponding to the convex rings. The sealing effect and the waterproof performance of the cold-shrinkable sheath are improved by the structure in which the support tube having the convex rings matches the ring grooves of the shrink-shrinkable sheath. The end covers improvesthe structural stability of the support tube, prolongs the service life of a product, and improves structural robustness of the product.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an indoor terminal of a 10kV cold-shrinkable cable. Background technique [0002] The cold-shrinkable terminal of the power cable is a kind of electric appliance that integrates waterproof, stress control, shielding and insulation, has good electrical and mechanical properties, and can be used for a long time under various harsh environmental conditions. It is widely used in various fields such as electric power, petrochemical industry, metallurgy, railway port and construction. It plays the role of connecting with other electrical equipment by assembling to the beginning and end of the cable line. [0003] However, during the use of the cold-shrinkable terminal, the support tube (2) needs to be used to support it for a long time. The longer the time, the lateral pressure on the support tube (2) will deform it and cause it to become a waste product; In addition, the openings at ...

Problems solved by technology

[0003] However, during the use of the cold-shrinkable terminal, the support tube (2) needs to be used to support it for a long time. The longer the time, the lateral pressure on the support tube (2) will deform it and cause it to become a waste product; In addition, the openings at both ends of the cold-shrinkable terminal are in a long-term stretched state, which may easily lead to insufficient elasticity and poor sealing performance, resulting in the entry of moisture from the outside and reducing its service life.
