15KV 200A Loadbreak Junctio

Comewill factory’s 15KV 200A Loadbreak Junction features an all-copper current-carrying path, ensuring reliable, consistent performance no matter the conditions.
It fully meets IEEE Standard 386 requirements, and is completely interchangeable with competitors’ products and other mating components that also comply with IEEE Standard 386. When installed with matching parts, this loadbreak junction delivers a fully shielded connection, ideal for loadbreak applications.

What is a 15KV 200A Loadbreak Junction?

A 15KV 200A Loadbreak Junction is a medium-voltage cable connection device used in power distribution systems to safely connect, branch, and sectionalize 15kV underground cables while allowing loadbreak (live switching) operation. It typically includes multiple 200A interfaces (such as 2, 3, or 4 ways) that are internally bused together, enabling flexible loop, tap, or splice configurations. Built to IEEE Standard 386, it ensures fully shielded, safe, and reliable operation in pad-mounted transformers, switchgear, and underground vault applications.

Junction with Bracket Dimensional Information

Loadbreak Operation Steps

1. Fasten the clampstick securely to the pulling eye.
2. Don’t apply any pulling force — just give the connector a slight clockwise twist to break the surface friction between the elbow and bushing.
3. Pull the connector straight out of the bushing with a quick, firm motion. Make sure to keep the connector away from any ground plane.
4. Place the connector on the proper accessory device, following that accessory’s operating instructions.
5. Use a clampstick to put an insulated protective cap (with drain wire connected to system ground) on any exposed energized bushing.
