JP Outdoor Integrated Distribution Box
Pole-mounted all-in-one box for 30–400 kVA transformers: metering, feeders and reactive compensation with short-circuit, overload, over-voltage and residual-current protection — IP54, the grid-upgrade workhorse.
- GB/T 7251.2-2023 LV switchgear and controlgear assemblies — Part 2
- GB/T 15576-2020 LV reactive-power compensation assemblies
- Designation: integrated distribution box · transformer capacity · main-circuit scheme No.
A cleaner, more reliable approach to MV switching
The HP-ELS series replaces SF₆ with environmentally friendly insulating media while keeping the proven safety and performance utilities expect from gas-insulated switchgear.
Product Overview
The JP series outdoor integrated distribution box combines metering, outgoing feeders and reactive-power compensation in one unit, with short-circuit, overload, overvoltage and earth-leakage protection. Compact, attractive, economical and practical, it mounts on the pole of an outdoor pole-mounted transformer — an ideal new-generation distribution product for urban and rural grid upgrading. Transformer capacity 30–400 kVA, rated operating voltage AC 400 V. It complies with GB/T 7251.2-2023 and GB/T 15576-2020.
