Description

Technical Field

[0002] A cable is a conductor covered with an insulation layer, a protective layer, and a shielding layer, used to transmit electrical or signal current and voltage. Based on voltage, cables can be classified as high-voltage cables and low-voltage cables. Low-voltage cables consist of three parts: the conductor, the insulation layer, and the protective layer. The conductor, used to conduct current, is generally made of multiple strands of copper or aluminum wire twisted together.

[0003] When degassing cable cores, the cable needs to be left to stand in a constant temperature environment for a period of time. The temperature of the constant temperature environment is generally maintained between 65 degrees Celsius and 85 degrees Celsius to reduce the by-products in the insulation to a low and stable level. Before inflating the cable, the cable end needs to be connected to the inflating equipment. However, the current clamps connecting the cable and the inflating equipment are cumbersome to operate and inconvenient for operators. Therefore, the existing technology needs to be improved.
