Distribution-class arresters protect pole-mounted transformers, reclosers and cable-to-overhead transitions on 11–33kV feeders. Compact MOV blocks, silicone-rubber or porcelain housings, optional disconnector and ground-lead isolator — engineered for decades of outdoor service in high-lightning regions.

Typical configurations shown. Final ratings, dimensions and test reports are confirmed per project datasheet — include your specification with the inquiry.
What is the difference between distribution and station class?
Station class arresters have higher energy absorption and lower protective levels for substation equipment; distribution class units are optimized for cost and size on feeders and pole transformers. We supply both.
Can arresters be mounted directly on transformers?
Yes, tank-mounted and bracket-mounted arrangements are common for pole transformers — specify your transformer and cross-arm layout with the inquiry.
Do you offer arresters for high-pollution coastal areas?
Yes, increased-creepage polymer housings are available for coastal, industrial and desert pollution zones.
