Directly molded polymer surge arresters for the reduction of environmental impacts.
As concern about global warming and environmental destruction increases, there is growing demand to reduce the environmental impact caused by power transmission and distribution equipment. Toshiba supplies directly molded polymer surge arresters with leading features and reduced environmental impact from manufacturing to operation, by using its excellent ZnO elements and silicone molding technologies based on its experience of manufacturing surge arresters since 1900.
1. Features of Toshiba polymer surge arresters
* Long-life cycle design
-Ideal designs and development and verification by sophisticated analysis techniques.
-Improved pollution characteristics by hydrophobic silicone rubber
-Improved water resistance by silicone rubber and ZnO elements (Lead-free glass is used on the sidesurface insulator)
*Improved safety for nearby operators and equipment
-No gas space in the arrester housing and pressure relief by splitting the silicone rubber
*Improved fire safety after pressure relief
-Self fire-extinguishing in emergency case of pressure relief by using high quality fire-retardant silicone rubber
*Improved protective characteristics by adjacent installation
-The expectation of longer life cycle of protective equipment thanks to improved protection by adjacent installation
lReduction of environmental impact during manufacturing -Reduction of environmental impact during purchasing transportation (Application of lightweight materials) -The application of silicone housing which does not need high-temperature sintering during manufacturing
*Reduction of manufacturing lead time -Self-manufacturing of ZnO elements and self molding of silicone housing
*Manufacturing for long-life cycle -Quality control by ISO9001 and ISO14000 certified manufacturing line
*Reduction of environmental impact during delivery transportation - Compact and lightweight design
- No need for special heavy equipment during installation - Application possibility of simple support structure
Toshiba polymer surge arresters continue to show optimum performances even under extreme environmental conditions with heavy pollution, or in industrial, coastal or desert areas thanks to the use of silicone rubber which remains hydrophobic throughout its life cycle. These long life cycle performances have been fully verified by detailed evaluations such as pollution tests, boiling tests, long-term life performance tests in a coastal area, and other tests.
*Compact and light weight design
Toshiba polymer surge arresters can be reduced in size and weight by applying ZnO elements with high energy absorption capability and the silicone directly mold design. Toshiba’ s surge arresters do not require special heavy equipment thanks to their compact and light weight design, making installation easier. In some case, installation of surge arresters on a very simple support structure or an additional structure can be available.
*Highly safe short-circuit performance
Toshiba’ s polymer surge arresters have a structure in which an internal section with stacked ZnO elements is directly molded by silicone rubber. Because there is no gas space in the arresters and thanks to the suitable design of the internal section, pressure can successfully relief by splitting the silicone rubber, thus preventing the internal parts from bouncing out in emergency case of a short-circuit caused by a surge arrester failure .
