Application areas:
Offset top expansion bus connectors are used for top expansion connections of SF6 insulated metal switchgear. They enable fully sealed and fully insulated connections between load switches and busbars, completely avoiding the fatal defects caused by high voltage exposure in harsh weather conditions. They are also easy to install and highly reliable.
Product Description
- The first-generation offset top-expansion bus connector includes:
- 1. WEB-15/DJ1 T-connector (T-joint)
- 2. WEB-15/SJ1 cross connector (four-way connector)
- 3. WEB-15/M1 busbar
- The second-generation offset top-expansion bus connector includes:
- 1. WEB-15/DJ1P T-connector (T-joint)
- 2. WEB-15/SJ1P cross connector (four-way connector)
- 3. WEB-15/M1P busbar
The connector body is made of high-quality SIR material. The busbar center distance can be customized according to customer requirements, and the busbar end mounting holes are available in round and oblong shapes. It is suitable for electrical systems with a rated voltage of 12kV and a rated current of 630A. The bushing interface conforms to DIN47636, EN50180 & 50181 standards. While meeting standard performance requirements, it is more streamlined and easier to install than the first-generation offset top-expanded busbar connector.
Wolong Electric is committed to continuous product improvement, therefore we reserve the right to change designs, dimensions, and data without prior notice.
