1. Features of Toshiba polymer surge arresters

Compact and light weight design

Highly safe short-circuit performance

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.

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.

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 .

2. Performance Toshiba’ s directly molded polymer surge arresters, which are the gapless ZnO element type, comply with IEEE standard C62.11-2012. These surge arresters cover the system voltages up to 362kV as summarized in Fig. 1. The principal characteristics of each type of surge arrester are summarized in Table 1.

Fig. 1 Covered range (system voltages)

Notes 1) Surge arresters with larger energy absorption capability are available.　　 2) The energy rating means the dissipated total energy per two shots of switching surge　　　　impulses that the surge arrester can withstand without losing thermal stability.

Notes 1) Various surge arresters outside of this range are possible according to the customer’ s needs. 2) “nn” in Arrester type denotes duty-cycle voltage.
