Polymer (Composite) Fused Medium Voltage Outdoor Disconnector (Isolator)

Polymer (Composite) Fused Medium Voltage Outdoor Disconnector (Isolator)

Product Description
Polymer (composite) fused medium voltage disconnectors are designed for safe switching of no-load circuits in power transmission and distribution systems. Manufactured in compliance with IEC and TSE standards, these disconnectors are available in 12 kV, 24 kV (17.5), and 36 kV voltage levels.

The main frame is hot-dip galvanized steel for maximum durability. Moving and fixed contacts are made of electrolytic copper with silver plating, ensuring minimum resistance and reliable conductivity. Outdoor models use porcelain insulators, while indoor options can be porcelain or epoxy.

Fused outdoor disconnectors are particularly used for the protection of pole-mounted transformers (≥400 kVA) and for safely disconnecting them when necessary. The mechanical interlock system ensures maximum operational safety.
