Elbow Surge Arrester

Detailed Description
17/50kV Elbow Surge Arrester with silicone rubber connector housing and installed on the 200A Load break bushing extender. It protects medium voltage network, e.g.: transformers, switchgears and cable. Incoming over voltage waves and voltage increase by reflection are limited.

Technical Specifications

The Technical Specifications of this Elbow Surge Arrester define its overvoltage protection parameters for medium-voltage distribution networks. The rated voltage of 17kV and impulse withstand voltage of 50kV establish the protective operating envelope for the EX-BLD-17/50kV model, ensuring reliable clamping of transient overvoltages. This Elbow Surge Arrester features a silicone rubber connector housing that provides excellent tracking resistance and hydrophobic performance, enabling reliable operation in polluted or humid outdoor environments. The EX-BLD-17/50kV is designed for installation on the 200A load break bushing extender, creating a compact protective assembly. As a critical Switchgear Insulation Component, this Elbow Surge Arrester protects transformers, switchgear, and cable terminations by limiting incoming overvoltage waves and suppressing voltage reflections that can cause insulation stress. The silicone rubber housing of this Elbow Surge Arrester also contributes to its lightweight construction and ease of field handling. Proper coordination of this Elbow Surge Arrester with other Switchgear Insulation Component devices ensures comprehensive surge protection for 17kV class distribution equipment.
