35kv Composite Pin Insulator

35kv Composite Pin Insulator Description:

composite pin insulator also named as polymer pin insulator, polymer line post insulator, silicone rubber pin insulator. 35kV polymer composite pin insulator is widely used for insulation and mechanical fixation of high voltage overhead transmission and distribution lines and transformer busbars. The insulation parts are composed of glass fiber resin mandrel, organic material sheath and umbrella insulator. It has the characteristics of small volume, light weight, high tensile strength and good anti pollution flashover performance.

35kv Composite Pin Insulator Schematic Diagra:

• 1. Shed connected with core by integral foring
• 2. The thinkness of housing > 3mm,unifirm to IEC Standard
• 3. Acid resistant,hight temperature resistant of epoxy fiberglass core
• 4. Metal end fittings,core and sheds connected by new crimping process
• 5. Hot galvanization and technology of rareearth aluminum coating to avoid coating shedding prolonging the service life

35kV Composite Pin Insulator Characteristics:

• 1. No flaw,crack in the surface and interior,each bar color uniform(green or light yellow).
• 2. Can withstand the sawing,milling,planning,drilling,lathe and other mechanical processing.
• 3. Internal thread can be tapping with screw tap,external thread can be polished,but not allowed to bear overload.
• 4. It has good damping,creep resistance,fatigue resistance,fracture resistance ,high temperature resistance,stress corrosion resistance etc.
