Heating causes of power cables and problems to be noticed in cable selection (I)
When the power cable passes through a certain load current, it is always higher or higher than the allowable high continuous working temperature of the cable (the allowable high temperature of cross-linked polyethylene insulated cable is 90 ℃), and the cable heats up for a long time. If the cause is not found and the fault is eliminated in time, the insulation thermal breakdown phenomenon will occur after the cable continues to power on and run, resulting in the interphase short circuit tripping of the cable, which may cause fire in serious cases. Cable heating during operation may be caused by the following reasons:

On March 19, the State Grid Corporation of the People's Republic of China (SGCC) held a mobilization meeting for the construction of power grids in the "three regions and two prefectures" in the deeply poor areas in Beijing. Kou Wei, General Manager of State Grid Corporation of China, said that in 2018, 6.6 billion yuan will be invested in the power grid to complete the tasks of isolated operation of county-level power grid interconnection, strengthening of connection with weak county-level power grid, relocation of poverty alleviation and power supply of secure housing, power supply of independent photovoltaic power supply villages and large power grids, and power supply of border defense forces. From 2019 to 2020, 14.4 billion yuan will be invested to improve the power supply guarantee capability.

Causes of uneven and bulged cable insulation surface (I)
Due to the different processing technologies such as extrusion temperature, extrusion speed and cross-linking speed used by silane crosslinked cable material from different manufacturers, the extrusion surface quality of low-voltage cable insulation core is also greatly affected. In the process of producing silane cross-linked polyethylene insulated wire core, the common phenomena and causes are as follows:

Causes of uneven and bulged cable insulation surface (II)
The common two-step silane crosslinked polyethylene is prepared by grafting silane with PE to produce crosslinkable PE (material A for short). In order to accelerate its crosslinking reaction, a masterbatch containing catalyst (material B for short) is prepared, and then materials A and B are uniformly mixed in a certain proportion. After extrusion molding, they are crosslinked in warm water. The main causes of insulation core quality problems caused by material stability are:

How to select heat-resistant wires and cables
With the rapid development of China's economy, the demand for high-temperature cables in special industries has shown a rapid growth step by step. The heat-resistant and high-temperature cables grow at a rate of 20% every year. As an important part of special cables, high-temperature cables have extremely strong vitality, and supply exceeds demand. China imports about 2 billion yuan from abroad every year for domestic construction.

How to select heat-resistant wires and cables?
Generally, plastic and rubber are used as insulating sheath for wires and cables. These materials are conventional engineering materials with rich sources, which can meet mass production and relatively low cost. However, for some special industries, such as petrochemical, steel, aerospace, shipbuilding, military, pharmaceutical, food, plastic machinery, boilers and other industries related to heat and high temperature,
