(1) Temperature. As the temperature increases, its resistivity decreases exponentially. This is because when the temperature rises, the thermal motion of the molecules intensifies, and the average kinetic energy of the molecules increases, which increases the probability that the kinetic energy of the molecules reaches the activation energy, and the ions easily migrate.

What are the factors that affect the resistivity of insulating materials?

(2) Humidity. The insulation resistance decreases as the humidity increases. The impact on porous materials (such as paper) is particularly significant, and the resistance of the dielectric surface is very sensitive to the impact of surface moisture. For electrical equipment, especially outdoor equipment, regular inspections of the insulation resistance of the equipment can prevent accidents.

(2) Impurities. Impurities increase, resistivity decreases, and the surface is contaminated by impurities and adsorbs moisture. Impurities directly increase conductive ions inside the dielectric. Impurities are particularly easy to mix into polar materials, and they can promote the dissociation of polar molecules.

Zhejiang Jingjing Insulation Material Co, Ltd is located in the gold district of Shangyu City Economic Development Zone, the fourth ring road, new Hiangyong Canal, Shangyu-Sanmen Highway, Shaoxing-Zhul Hig/way to the west, Hangzhou-Ningbo Railway,104 National Highway to the south,329 National to the east and Shanghai Hangzhou-Ningbo Highway io the north.

There are 5 kilometers from new Hangzhou-Ningbo nigh-speed rail station, each 50 kilometers from Xiaoshan Iriemationat Airport and Ningbo Intermallonaf Airport. The extremely convenient traffic network makes the superior geographical environment and investment climate for the industrial park.

The total area of ​​our company is 7653 square meters. The construction area is 12000 square meters. The total investment is 10 million RMB.
The annual sales reach 30 million RMB. And the rate of greening reaches 20%.
