Insulators SHPU-10
Line composite silicon pin insulators SHPU were manufactured by using brand new materials and constructive solutions that were never used before. Solutions that were found in manufacturing process were also used in production of other insulator types.
The rubber part in SHPU insulator is placed under high pressure between cap and metal tube flange. Function of insulating body is similar to function of silent blocks suspension of a vehicle. Insulator has minimal quantity of parts: metal grounded tube for traverse probe, dielectrical anti - trаcking silicone rubber sealant and metal cap for wiring. Thermal withstand of such insulator is more than 350°C, and is limited by melting temperatures of components. Withstand of SHPU insulator to temperature differences (thermoshock) is more than 420°C. Insulator withstands temperature differences from -70°C up to +350°C. Glassplastic used for manufacturing of power dielectrical body of insulator was reinforced with stable to lixiviation glass-roving. This allowed significantly increase the lightning impulse withstand of SHPU insulator. Original fitting construction allows quick exchange of old ceramic insulators to new composite silicon pin insulators. Mounting time is under 30 seconds.
Operating time is 30 years in open air and high pollution enviroment conditions. Insulators are suitable for installation in far northern areas. For such kind of installation insulators are supplied with special steel caps, which are able to withstand extremely low temperatures down to - 80°C. A possibility of installation in remote regions (swamps, mountains, forests…) makes them irreplaceable for using in oil and gas industry.
