Geothermal pumps reduce waste

At present, the total direct use of the country has reached 2410 MW, ranking first in the world, but the level of utilization and efficiency is relatively low, and the energy utilization rate for the temperature range of 25°C to 50°C is poor. In order to a

Main factors affecting cable insulation resistance

The insulation resistance of wire and cable products mainly measures the volume resistance of the cable insulation, and the surface resistance is not measured. There are many factors affecting the resistance value of the wire and cable. In practice, the three main factors affect the insula
