ANSI standard dead end composite insulators , the housing and sheds material are silicone rubber , this polymer has inherent resistance to UV and corona . it also provides a water repellent surface to decrease flashover.
The insulator production procedure is moulded silicone on fiber glass core, this allows variable leakage distances for a fixed insulator length, an the eliminates moldines that can ecourage leakage currents.
The metal fittings must be cramped to the fiberglass core .
the insulator rubber material is HTV type .
When we make design on deadend insulators , the insulator sheath thcikness is Min. 3mm ,which can reduce the electric field strength within the FRP rod .
All the deadend insulator comply with ANSI Standard . that means those insulators are commonly used in American Markets , USA, South American countries etc.
Good Advantages:
HIVOLT dead end insulators are in high quality both mechanical and electrical performance, we guarantee you every pieces of insulator are well tested before transported out of factory .
The insulator can only be sent out after passing related test items.
the HIVOLT dead end insulator has good experience to work more than 20 years.
