Toshiba’s polymer surge arresters have low environmental impact thanks to the use of silicone rubber which remains hydrophobic throughout its life cycle (Fig. 1), consequently a continuous conductive layer is not formed on the surface of surge arresters by moisture and/or pollution materials. Therefore, the surge arresters continue to show optimum performances even under extreme environmental conditions with heavy pollution, or in industrial, coastal or desert areas. In addition, the surge arrester have been made highly water resistant by applying water-resistant glass to the side-surface insulator (Fig. 2) and using water-resistant silicone rubber (Lead-free glass for the glass coating is another environmental benefit.) The best seal strength of silicone rubber is achieved by optimal selection and application of primer. These long life cycle performances have been fully verified by detailed evaluations such as pollution tests, boiling tests in salt water (Fig. 3), long-term life performance tests in a coastal area (Fig. 4), heat-cycle tests, and other tests.

Toshiba’s polymer surge arresters feature directly molded silicone rubber housing instead of the conventional porcelain housing. Since silicone rubber is approximately 50 % lighter than a porcelain housing, environmental impact during transportation of purchased materials is significantly reduced. We also substantially reduced the size and weight of the surge arresters compared with porcelain surge arresters by applying ZnO elements with high energy absorption capability and the silicone directly mold structure. Therefore, the environmental impact during transportation for delivery is significantly reduced. Figure 5 compares porcelain and polymer surge arresters for the 245 kV system. The weight is reduced from 375 lbs (170 kg) to 144 lbs (65kg) and the height is also reduced with maintaining proper creepage distance because the complicated shed design was achieved by silicone injection.

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 relieve 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 (Fig. 6). This feature ensures the safety of nearby operators and equipment during pressure relief. In addition, the use of high-quality incombustible silicone rubber makes the surge arresters self-extinguishing soon after pressure relief.

Toshiba’s surge arresters do not require special heavy equipments thanks to their compact and light weight design, making installation easier. In some cases, in addition to simplification of support structure (Fig. 7), the support structure for adjacent equipments was also used (Fig. 8). The safer pressure relief of the Toshiba polymer surge arresters enables them to be installed near other equipments.

The delivery lead time of Toshiba’s polymer surge arresters has been reduced by self-manufacturing of ZnO elements (Fig. 9) and silicone molding. They are manufactured in ISO9001 and ISO14001 certified manufacturing l ines under a str ict qual i ty and environmental control system.

Our highly experienced development staff develop and design Toshiba’s polymer surge arresters with using pioneering analysis techniques. The flow of silicone rubber during injection (Fig. 10) is also analyzed and the best injecting condition is obtained. These manufacturing technologies result in long life cycle performance in the field.

Toshiba’s directly molded polymer surge arresters, which are the gapless ZnO element type, comply with IEEE standard C62.11-2005. These surge arresters cover the system voltages up to 420 kV as summarized in Fig. 11. Standard type and high mechanical strength type are available for different applications. The principal characteristics of each type of surge arrester are summarized in Table 1.

2. Performance Figure 12 shows the temporary over-voltage capability. Toshiba’s directly molded polymer surge arresters are available for all ratings. The curve represents the recommendation temporary over-voltage capability and defines the duration and magnitude of temporary over-voltages that may be applied to the surge arrester until the applied voltage reduces to the normal continuous voltage.
