The JP Series Integrated Distribution Box is a multi-functional outdoor power solution designed for low-voltage (0.4kV) networks. Engineered for extreme environmental resilience, this cabinet combines power distribution, metering, compensation, and circuit protection into a single, compact stainless steel enclosure.
Commonly referred to as the "JP Cabinet," it is widely used in rural power grid transformations and as a Photovoltaic (PV) Grid-Connected Box. It serves as the critical interface between solar inverter outputs and the utility grid, ensuring safe power export while providing real-time metering and reactive power compensation to maintain grid stability.
Corrosion-Resistant Stainless Steel: Constructed from high-grade 304 or 316 Stainless Steel, providing a 25-year service life in high-humidity, salt-spray, or industrial-pollution environments.
All-In-One Integration: Consolidates the main incoming switch, energy meter, reactive power compensation controller (capacitors), and outgoing feeders, reducing installation time and site footprint.
Outdoor Weatherproof Rating (IP44/IP54): Features a sloped rain hood, hidden hinges, and high-performance EPDM gaskets to prevent water ingress and dust accumulation.
Advanced Safety Protection: Integrated with Residual Current Devices (RCD), Surge Protective Devices (SPD), and Overcurrent/Short-circuit protection to secure the grid-connection point.
Thermal Management: Designed with natural convection ventilation louvers and optional internal heaters to prevent condensation and ensure stable operation in temperatures from -25°C to +55°C.

Solar PV Grid-Connection: The primary AC collection box for commercial rooftop solar or rural distributed PV projects, managing grid synchronization.
Rural Power Grid Transformation: Replacing outdated pole-mounted fuse boxes with smart, metered, and compensated distribution hubs.
Industrial Site Power: Providing a rugged outdoor power source for construction sites, irrigation systems, and remote mining facilities.
Urban Street Lighting: Controlling and metering high-density LED lighting circuits with automated timing and protection.
Smart Metering Ready: We provide dedicated compartments for utility-grade smart meters, allowing for seamless data collection and remote energy monitoring.
T2 Copper Busbar System: All internal power connections use high-purity tinned copper busbars to ensure maximum conductivity and zero oxidation at contact points.
Double-Door Design: Our larger units feature a double-door layout (front and back or split-front) with high-security 3-point locking mechanisms to prevent unauthorized access.
Bespoke Internal Layouts: We offer full customization based on your Single Line Diagram (SLD), including specific breaker brands like ABB, Schneider, or CHINT.
Q: Can this box be mounted directly onto a utility pole?
A: Yes. We offer specialized heavy-duty stainless steel "U-bolt" mounting kits designed specifically for pole-mounted installations in rural or urban environments.
Q: Does it include the reactive power compensation capacitors?
A: Standard configurations include automatic compensation banks to improve power factor. We can customize the KVAR rating based on your specific load profile.
Q: How does the cabinet handle extreme summer heat?
A: Along with the natural ventilation louvers, we use reflective stainless steel finishes and can include internal cooling fans triggered by an integrated thermostat.
