Description

A kind of 35 kilovolts of cold-contraction type outdoor cable terminals
Technical field
The present invention relates to power domain, especially, relate to the electric cable accessories in a kind of mesolow transmission system, more specifically, relate to a kind of cold-contraction type outdoor cable terminal.
Background technology
Cold-shrink cable terminal utilizes elastomeric material to inject sulfidization molding in factory, then through expanding, serve as a contrast the parts being formed various electric cable accessories with plastic spiral supporter.During in-site installation, these predilation parts are enclosed within cable end piece after treatment or joint, extract the plastic spiral bar (supporter) of inner support out, be pressed on the electric cable accessories that cable insulation is formed.Because it is at normal temperatures by elastic recovery force, instead of the fiery heat shrink of picture thermal contraction electric cable accessories, therefore be commonly called as cold events electric cable accessories.
35 kilovolts of cold-contraction type outdoor cable terminals are the cable terminals in national grid electric power course of conveying, are indispensable parts in electric power system.
At present, domestic 35 kilovolts of cold-contraction type outdoor cable end products are more, and kind is uneven, and the product that user generally adopts mainly has following two kinds of versions:
1) cold-contraction type rubber terminal bodies stress cone structural formula
Namely, in the built-in rubber terminal bodies of tearing polypropylene spiral support bar of one, cable insulation overcoat, after being removed by spiral support bar, terminal bodies meeting elastic shrinkage, makes terminal bodies inwall and cable insulation resilient engagement.As the shrink cable termination of electric cable accessories Manufacturing Co., Ltd of Shenyang League of Nations, terminals material usage is large, and wall is thicker, and nargin is comparatively large, wastes a large amount of raw material, and after expansion, qualification rate is low, thus wastes a large amount of raw material, significantly adds entreprise cost.Also have a kind of shrink cable termination, terminals material usage is not enough, and wall is thinner, and performance is low, easy to crack.
2) cold-contraction type rubber terminal bodies stress tube structural formula
Namely adopt stress tube that the material of high-k performance is made into improve electric field stress, run in long-time electric field, the change of temperature, external environment condition all will make stress control material aging, the specific insulation of the stress control material after aging can change a lot, specific insulation becomes large, stress control material has become insulating material, do not have the effect improving electric field, specific insulation diminishes, stress control material has become electric conducting material, cable is broken down, thus affects the use of product.
