What is JP Cabinet (Low-Voltage AC Integrated Distribution Box)?

1. Overview

JP Cabinet (Low-Voltage AC Integrated Distribution Box) is an integrated power distribution product installed on the low-voltage side of transformers, integrating power distribution, metering, protection, control and reactive power compensation functions. It consists of three compartments: switch compartment, metering compartment and compensation compartment. Its main components include circuit breakers, metering and measuring current transformers, energy meters and data collection terminals, integrated power distribution control terminals, capacitor switching units and self-healing low-voltage shunt capacitors.

With advantages in power distribution, control, management, harmonic suppression and reactive power compensation, the integrated distribution cabinet has been widely applied in the renovation of urban and new rural power distribution networks. This product can improve the power factor of low-voltage distribution networks, reduce power losses, enhance power supply quality at load terminals, and raise the utilization rate of transformers and transmission lines. It is of great significance for energy conservation and loss reduction, strengthening the safety and stable operation of power grid systems, and improving economic benefits for users.

2. Applicable Standards for ZPD Series Integrated Distribution Cabinets Manufactured by Our Company

· IEC 439-1 Low-voltage switchgear and controlgear assemblies

4. Structural Characteristics

The cabinet body is available in vertical and horizontal types. The outer shell is fabricated from 2 mm stainless steel plate via multi-edge folding forming process (or stainless steel double-layer sandwich honeycomb composite plate with flame retardant, environmental-friendly, heat insulation and anti-condensation properties). Adopting special stainless steel welding technology, the cabinet features high overall structural strength after forming, mirror-smooth surface with invisible welding seams. Internal mounting beams (plates) are hot-dip galvanized to guarantee no rust within 20 years.

The cabinet is equipped with front and rear double doors for convenient operation and maintenance. High-elasticity anti-aging sealing strips are fitted around all door frames, and each door is installed with both concealed and exposed locks. The exposed lock is equipped with a rain shield for anti-blocking and rust prevention. The fully enclosed metering compartment is fitted with lead sealing devices.

Rainproof and foreign-matter-proof cable conduits for incoming cables are mounted on cabinet sides. Vent holes and cable outlet holes are punched on the cabinet bottom, while ventilation ducts and wire mesh screens are arranged on the top. The cabinet is waterproof, rust-proof, dust-proof and foreign-matter-proof, with a protection grade of IP54.
