Problems solved by technology

The main disadvantages of this method are: ①Before sample detection, the sample needs to be cured in a curing room with constant temperature and humidity. The curing conditions are harsh, and supporting equipment is required, which increases the detection cost; ②It needs to be cured for more than 16 hours before measurement , and the measurement time is 30 minutes, the entire measurement cycle is long, so the detection speed is slow; ③When the sample is tested, the sample is carried out at a temperature not lower than 935°C, which consumes a lot of energy; moreover, it takes a long time to heat up to 935°C , which further increases the measurement cycle; at the same time, operating at a higher temperature is more harmful to the experimental operators. In addition, the equipment works at high temperature for a long time, and the life of the equipment will be greatly reduced, so the safety of the detection is poor.

Abstract

The invention discloses a wire and cable manufacturing method. The method specifically comprises the steps that 1 core wire conductor metal drawing is carried out; 2 the drawn core wire conductor metal is annealed and stranded; 3 the insulation material of a wire and cable is prepared and uniformly stirred for spare; 4 the insulation material acquired in the step 3 is used as a starting material,and the starting material and a core conductor are made into a wire or cable; and 5 the qualified wire or cable made in the step 4 undergoes single or multiple two-step continuous chemical crosslinking, wherein the chemical crosslinking steam pressure is 0.8 to 1.5MPa, and the temperature is 170 to 190 DEG C. The prepared wire and cable are halogen-free, low-smoked and flame-retardant. The invention further discloses a method used for detecting the wire and cable manufactured by the method.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, and relates to a method for manufacturing electric wires and cables, and also relates to a method for detecting electric wires and cables. Background technique [0002] At present, most of the wires and cables in the domestic market use polyvinyl chloride with general additives as the insulation or sheath layer. not good. Actual operating life is short. Especially in the case of heat, sunlight, and fire, it will cause degradation, produce hydrogen chloride gas, and cause personnel to be poisoned and die. Therefore, in order to eliminate the toxicity caused by the degradation of halides, some people now use other polymers instead of polyvinyl chloride to produce wires and cables, but when such wires and cables encounter high ambient humidity or are soaked in water during use, their insulation The performance drops sharply, seriously affecting the safe use of wires and cables. ...
