Description

technical field The invention relates to the technical field of power cable cutting devices, in particular to an automatic cutting device for insulating layers of high-voltage cables. Background technique High-voltage cables can be roughly divided into two parts, one of which is the outer structure, which mainly includes outer sheath, armor layer, inner sheath and shielding layer. The other part is the internal structure, which mainly includes the outer semiconductive layer, the main insulating layer, the inner semiconductive layer and the wire core. The external structure requires relatively low machining accuracy, while the internal structure directly interacts with the electromagnetic field of the high-voltage cable. In order to achieve insulation and shielding, the internal structure requires relatively high machining accuracy. The internal structure of high-voltage cables can be divided into two types according to the voltage level. The voltage level of 10kV and below...
