The energy-saving cable tray has a large heat dissipation area because of concave convex corrugated. The heat dissipation structure of upper and lower air-conditioning exchange is also designed to maximize the volatilization of the heat generated by the cable conductor inside the cable tray, reduce the resistance and loss of the circuit, improve the utilization rate of power, and realize the energy-saving effect.

At present, China still has a long way to go compared with developed countries in terms of line loss reduction and power utilization rate. The power utilization rate in Japan is 57%, and that in the United States is 51%. Only 31% of China's urban and rural power grids have not been transformed, and only about 40% after transformation. It can be seen that the development of energy-saving technology has a long way to go.

Most of the power supply objects of energy-saving cable tray laying cables are the end-users of low-voltage distribution, and the loss of low-voltage lines and power utilization rate do not get very good attributes. The electricity charge is calculated according to the electricity meter, and the users can not fully face up to the loss on the line. However, more than 50% of China's electricity demand should be consumed by end users. The end users of low-voltage distribution system can reduce the line loss and improve the power utilization with the help of energy-saving cable tray.

If the factory uses more electricity, the annual electricity cost is more than 50 million yuan. If the energy-saving cable tray is used, according to the energy saving rate of 2.05%, the annual electricity cost can be saved by 1.025 million yuan. In this way, if the energy-saving cable tray is widely promoted throughout the country, great social and economic benefits will be achieved.

According to the detected data, the cooling effect of the energy-saving cable tray is good, which can reduce the temperature of the built-in cable by about 10 ℃, delay the aging of the cable insulation layer, extend the service life, and reduce the frequency of fire accidents caused by short circuit caused by temperature rise.
