Steema 11kv Surge Arrester
At Steema Transformers & Electricals (U) Ltd, we offer high-performance Zinc Oxide Surge Arresters specifically designed to safeguard your 11kV electrical systems from damaging over-voltage events. Our surge arresters are critical components for protecting valuable equipment and ensuring the continuous reliability of your power network.
Product Introduction
The STEEMA 11kV Silicone Composite Polymer Gapless Metal Zinc Oxide Lightning Surge Arrester is an advanced power protection device meticulously engineered to shield electrical systems from transient and switching overvoltage events. It features an exceptionally fast response time and high discharge capacity, effectively protecting insulation and ensuring overall system stability. Our arresters are designed with low residual voltage and boast excellent energy absorption capacity, all encapsulated in a simple, durable structure to ensure a long and reliable service life.
Encapsulated in a robust silicone composite polymer housing, our Metal Oxide Arresters (MOA) combine superior insulation with outstanding mechanical strength. This design provides powerful protection even in extreme environmental conditions. The polymer housing makes them explosion-proof, highly anti-aging, and weather-resistant, with excellent hydrophobic and dielectric properties.
Steema Transformers & Electricals (U) Ltd’s 11kV surge arresters deliver unparalleled reliability and performance. They are perfectly suited for a wide range of applications within power generation, transformation, and distribution systems, including substations, overhead lines, and industrial installations.
