ABB Transmission and Distribution has released a new range of outdoor surge arresters suitable for a variety of applications such as protection of distribution equipment, capacitor banks, cables, motors and railway equipment.

The new arresters, called the POLIM series, are manufactured with a housing of silicone polymer which, when compared to other polymeric material, has the highest resistance to severe environmental pollution such as water, salt, industrial pollution and others.

ABB arresters incorporate the latest metal-oxide technology, the metal oxide blocks used are manufactured by ABB to rigorous quality standards and offer the best possible protection margin which increases the lifetime of the protected equipment.

The POLIM Series can be used in system voltages from 4 to 36kV and is applicable to many special requirements such as IEC line discharge class 1 to 4 or ANSI ‘distribution normal duty’ to ‘station class high energy’.
