Abstract
The utility model relates to cold-shrink expansion equipment with lubricating oil, aimed at solving the problems that in the prior art, an expansion die directly contacts with the inner wall of a cable accessory during expansion, friction is severe, and the cable accessory tends to be scratched. The cold-shrink expansion equipment is characterized by comprising a taper head of the expansion die, the cable accessory, the expansion die and fixed plates, wherein the expansion die is equipped with the taper head of the expansion die, the cable accessory is placed between the fixed plates, and the taper head of the expansion die and the inner of the cable accessory are equipped with the lubricating oil. According to the cold-shrink expansion equipment with the lubricating oil, friction between the expansion die and the inner wall of the cable accessory can be reduced, and the cable accessory can be well protected during expansion.
Description
Technical field
The utility model relates to a kind of expansion device of electric cable fitting, relates in particular to a kind of shrinkage expansion device with lubricating oil.
Background technology
Chilling shrink type cable accessory has the characteristics such as volume is little, easy to operate, and product specification is few.Before installing and using, chilling shrink type cable accessory is in the high-tension state, easily causes electric cable accessories permanent deformation or relaxation etc. and be in for a long time the high-tension state.Therefore for requiring higher 110kV and above cold-contraction type cable to adopt on-the-spot expansion, dispatch from the factory before complete expansion and relatively require lower 35kV and following chilling shrink type cable accessory generally to adopt both at home and abroad.
Present chilling shrink type cable accessory at factory's intramedullary expansion; during expansion, dilatation mold directly contacts with the electric cable accessories inwall; friction is serious; easily scratch electric cable accessories; in view of this; how to reduce the friction of dilatation mold and electric cable accessories inwall, protect electric cable accessories when expansion, just seem extremely important.
Summary of the invention
The purpose of this utility model is: a kind of shrinkage expansion device with lubricating oil is provided, and when having expansion to solve prior art, dilatation mold directly contacts with the electric cable accessories inwall, and friction is serious, easily scratches the problem of electric cable accessories.
The technical scheme that the utility model technical solution problem adopts is: a kind of shrinkage expansion device with lubricating oil, it is characterized in that: comprise the dilatation mold conical head,, electric cable accessories, dilatation mold, fixed head, dilatation mold is provided with the dilatation mold conical head, electric cable accessories is placed in the middle of fixed head, and dilatation mold conical head and electric cable accessories inside are provided with lubricating oil.
The beneficial effect that the utility model reaches is: adopt the utility model to reach the friction that reduces dilatation mold and electric cable accessories inwall, protect the beneficial effect of electric cable accessories when expansion.
