Description
Technical field
The present invention relates to power equipment accessories technical field, more particularly to a kind of cold shrinking power cable adjunct predilation equipment and side
Method.
Background technology
Cold-shrinking cable accessory is a kind of common electric power attachment, and the China that Authorization Notice No. is 101814708 B of CN is specially
Profit discloses a kind of method for pre-expanding of cold-shrinking cable accessory, including following operating procedure：
A) by several steel wires pass through cold-shrinking cable accessory to be expanded, using advance corresponding intrument workbench first,
The both ends of expansion disk difference clamped wire in second station；
B) the synchronous Pan Kou and taut wire for expanding two expansion disks, expands cold-shrinking cable accessory, by shrinkage using steel wire
Type cable accessory enlarged-diameter keeps steel wire support state to predetermined amount；
C) according to dilator bar of the cold-shrinking cable accessory size selection one end with expansion conehead, support tube activity is nested with
An end cap is arranged on the dilator bar of spreader cone back of head, and in the opposite dilator bar other end of expansion conehead, by support tube pressure
