MNS Low Voltage Standoff Insulator With Low Voltage Switchgear 

Features:

Therefore, the area of pollution should be strengthened insulation or the use of anti-fouling insulator, its climbing distance(climbing distance to rated voltage ratio) should be higher than the normal type. Compared with AC insulators, DC insulators have poor electric field distribution, adsorbed dirt particles and electrolysis, and low flashover voltage.

Mechanical performance: Insulators are often subjected to the gravity and tension of wires, wind, ice-covered weight, insulator self-weight, conductor vibration, equipment operating mechanical force, short circuit electrical power, earthquake and other mechanical force. The relevant standards have strict requirements for mechanical performance.

Thermal performance: Outdoor insulators require the ability to withstand abrupt changes in temperature. For example, porcelain insulators require several cold and hot cycles without cracking. Due to the current passing through the insulated sleeve, the temperature rise of the parts and insulation parts and the allowable short-term current value must meet the relevant standards.
