Insulators in the use of power equipment plays an important role

   Insulators in the use of power equipment plays an important role, can effectively ensure the normal operation of the line, so the insulator installed in the overhead lines must have a good quality assurance, to ensure that can withstand relatively large pressure and load.

   Insulator is a kind of isolated electrical equipment, it is a good insulation equipment, plays an important role in the power equipment, can effectively protect the electrical equipment from damage. Insulators can be divided into different types, different types in use with different value in the protection of power equipment plays an important role. Insulators according to the structure can be divided into high and low voltage insulators, pollution insulators, suspension insulators and casing insulators, these insulators in different areas and industries to use in the industry to show good performance. In the overhead lines used in the insulators, commonly used pin insulators, butterfly insulators, suspension insulator porcelain, ceramic cross arm, rod insulators and tensioning insulators, these insulators are mainly used in overhead lines, with Good insulation properties. Insulator electrical faults are mainly flashover and breakdown of two. Flashover occurs in the insulator surface, can be seen traces of burns, usually do not lose insulation properties; breakdown occurs in the insulator inside, through the iron cap and iron feet between the porcelain discharge, the appearance may not trace, but has lost insulation performance, The insulator may be completely destroyed by the generation of an arc. For breakdown, should pay attention to check the iron feet of the discharge traces and burns.
