Polymer Distribution Surge Arresters are designed to protect distribution transformers, overhead power lines, and electrical equipment against lightning and switching over voltages. They use metal oxide varistor (MOV) technology and a silicone rubber housing to provide reliable overvoltage protection in outdoor environments.

Key Features

• Reliable Overvoltage Protection: Helps protect electrical equipment against lightning and switching surges.
• Silicone Rubber Housing: Provides outdoor insulation and resistance to environmental exposure.
• Metal Oxide Technology: Offers nonlinear voltage-current characteristics for effective surge limitation.
• Compact Design: Suitable for pole-mounted distribution equipment.
• Multiple Voltage Ratings: Available in different voltage classes according to system requirements.
