The JP Series Low-Voltage Integrated Distribution Box is an all-in-one outdoor solution specifically designed for power grid transformation and urban/rural distribution networks. It integrates four core functions into a single, compact enclosure: Power Distribution, Metering, Protection (Short circuit/Overload/Leakage), and Reactive Power Compensation.
Commonly installed on pole-mounted transformers or as a standalone outdoor pedestal, the JP box ensures that power is distributed safely while simultaneously improving the power factor of the network through automatic capacitor switching. Fabricated from high-grade stainless steel or SMC materials, it is engineered to survive 25+ years in extreme outdoor environments, ranging from coastal humidity to arid heat.
Smart Reactive Power Compensation: Equipped with an intelligent controller and high-quality power capacitors to automatically track the load and switch capacitors. This reduces line losses and improves transformer efficiency by maintaining a high power factor (cos φ ≥ 0.92).
Comprehensive Grid Protection: Includes integrated Molded Case Circuit Breakers (MCCB) and Residual Current Protection (RCD) to safeguard the local grid against overloads, phase failures, and earth leakage.
Weatherproof "Double-Layer" Construction: Features a double-door, double-layered roof design to prevent solar radiation from overheating internal components. High-elasticity PU gaskets ensure IP44/IP54 protection against driving rain and dust.
Corrosion-Proof Enclosure Options: Available in SUS304 Stainless Steel (brushed finish) or SMC (Sheet Molding Compound). Both materials are inherently resistant to salt spray, UV degradation, and chemical pollutants.
Independent Metering Compartment: Designed with a separate, sealable section for energy meters, preventing unauthorized access and ensuring accurate utility billing.

Rural Power Grids: Ideal for pole-mounted transformer stations in agricultural areas where reactive power compensation is critical for line stability.
Urban Residential Areas: Outdoor distribution and metering for apartment complexes and municipal street lighting networks.
Industrial Parks: Localized low-voltage distribution for temporary construction sites or small-scale industrial workshops.
Renewable Energy Sites: Metering and power quality management for small wind and solar collection points.
Turnkey Manufacturer Expertise: We provide fully-assembled boxes pre-wired to your Single Line Diagram (SLD). Internal components can be specified from brands like Chint, Delixi, or Schneider.
Anti-Condensation Design: Every cabinet includes ventilation louvers and can be equipped with automatic heaters to manage humidity, preventing internal arcing in cold or damp climates.
Space-Saving Efficiency: By consolidating metering and compensation into one box, you save on civil engineering costs and reduce the visual clutter of utility poles.
Seismically Reinforced: Our heavy-duty stainless steel shells are designed with reinforced internal bracing to withstand high-vibration environments and extreme wind loads.
Q: Can this box be customized for specific utility meter sizes?
A: Yes. The internal metering plate is fully customizable to fit various smart meters or traditional analog meters. We also provide transparent viewing windows for easy reading.
Q: What is the benefit of the SMC enclosure over Stainless Steel?
A: SMC (fiberglass-reinforced polyester) is completely non-conductive, offering extra safety in public areas. It is also 100% rust-proof and slightly better at thermal insulation than metal.
Q: Does the compensation part use contactors or thyristors?
A: We offer both. For standard loads, we use specialized capacitor switching contactors. For rapidly changing loads, we can integrate thyristor-switched modules for high-speed response.
