Description

TECHNICAL FIELD

[0001] The utility model relates to cable processing technical field especially, it is a kind of chamfer cutting device for cable insulation layer. BACKGROUND

[0002] The content of this part only provides the background information related to the utility model, which can not constitute the prior art.

[0003] Alternating current transmission has the advantages of high transmission efficiency and small energy loss, and is widely used for long-distance or super-long-distance power transmission. When long-distance or super-long-distance transmission is to be realized, a single cable joint needs to be processed so that multiple cables are spliced together. At the cable joint, the semiconductive layer of the cable needs to be stripped, and an electric field concentration phenomenon will occur at the end position of the stripped semiconductive layer, and the electric field strength here is very high. Therefore, the insulation layer near the conductor connection end is usually cut into a chamfered conical surface, and then wrapped with an overwound insulation, and the overwound insulation forms a chamfered conical surface at both ends. Changing the potential distribution of the insulation surface plays a role in uniform electric field, ensuring the safety of the joint.

[0004] To ensure sufficient safety, the forming of the chamfered conical surface requires a relatively high degree of accuracy, and currently, a glass cutter or a special cutter is used to manually cut out the chamfered conical surface. This method is time-consuming and labor-intensive, and the chamfered conical surface cut out is often not accurate and smooth, directly leading to uneven cable head installation quality, which poses a hidden danger to the subsequent cable operation. Although there are some devices that assist in chamfer cutting, most of the existing devices are designed for a limited range of cable diameters. Moreover, these devices are mostly complex in structure, cumbersome to operate, low in efficiency, and low in cutting quality.
