Low-Voltage Distribution Cabinets (JP Cabinets)

Product Overview

The JP Cabinet (Low-Voltage Comprehensive Distribution Cabinet) is a new type of integrated equipment specially designed for outdoor low-voltage distribution systems. It is widely used in urban and rural grid renovation projects, industrial and mining enterprises, street lighting, and residential communities. Integrating multiple functions including power distribution, energy metering, control, protection, and automatic reactive power compensation, it is the ideal low-voltage complete set device that meets the requirements of standardization, miniaturization, and outdoor installation for both rural and urban low-voltage distribution networks.

Core Technologies & Structural Features

●High Protection & Weather-Resistant Design

The cabinet body typically adopts a spray-coated or galvanized angle steel frame, clad with stainless steel plate (or SMC composite material), with a matte surface finish to eliminate glare. It features comprehensive "Six Protections": rain-proof, dust-proof, theft-proof, leakage-proof, lightning-proof, and electromagnetic interference-proof. With a protection rating of IP44 and above, it ensures stable operation in harsh outdoor environments ranging from -40°C to +55°C.

●Safe & Independent Compartment Structure

The interior of the cabinet is strictly divided into four independent compartments: the metering room, isolating switch room, feeder switch room, and reactive power compensation room. The energy meter and metering current transformers are housed in the same compartment, isolated from other functional rooms by sealed partition plates. The doors support both lead sealing and lock sealing. The compensation room is separated from other rooms by a minimum 2mm galvanized steel plate, effectively preventing fault propagation.

●Intelligent Control & Comprehensive Protection

Equipped with an integrated distribution monitoring and reactive power compensation controller, it supports cyclic switching, coded switching, and fuzzy logic automatic switching modes, with a response time ≤20ms, capable of maintaining the grid power factor above 0.95. It also provides comprehensive safety protection functions including overvoltage, undervoltage, overload, short circuit, phase loss, zero-sequence over-limit, and residual current (earth leakage) protection.

●Waterproof In/Out Cable Design

Cable entry is via the side of the cabinet, equipped with dedicated stainless steel waterproof elbows and rubber gaskets. Cable exit supports both side and bottom configurations. All cable entry/exit points are reliably sealed with a minimum 2mm epoxy resin board to effectively prevent rainwater and small animals from entering.

 Ordering Information

Dear Customer, to ensure your ordered JP Cabinet precisely matches the distribution area and grid renovation requirements, please provide the following detailed technical information before placing your order:

●Core Electrical Parameters & Drawings

  1. Primary System Diagram & Scheme Number: Please provide a detailed main circuit wiring scheme (primary system diagram). If drawings are not yet available, please specify the required functional scheme combination (e.g., 01—Distribution + Compensation + Metering; 02—Distribution + Compensation; 03—Distribution + Metering, etc.).
  2. Transformer Capacity & Compensation Requirements: Specify the rated capacity (kVA) of the distribution transformer matched with the JP Cabinet, as well as the total reactive power compensation capacity (kvar) and compensation mode (three-phase common compensation, split-phase compensation, or hybrid compensation).
  3. Switchgear & Protection Configuration:

○ Specify the rated current and brand requirements for the main incoming isolating switch and outgoing molded-case circuit breakers (MCCB).

○ Whether a high-breaking automatic reclosing earth leakage comprehensive protector is required, and specify the leakage operating current and time delay.

○ Specify the transformation ratio and accuracy class for measuring CTs and metering CTs.

●Structural & Appearance Requirements

  1. Cabinet Material & Dimensions: Specify the outer shell material (e.g., 201/304 stainless steel, SMC composite material, etc.) and stainless steel plate thickness (standard requirement> 1.5 mm). Confirm the cabinet door configuration (e.g., front and rear double doors on four sides) and any dimensional constraints.
  2. Cable Entry/Exit Method: Specify the cable entry and exit method (side-in side-out, bottom-in bottom-out, or side-in bottom-out), and provide the approximate specifications of the incoming/outgoing cables so that suitable waterproof elbows and sealing holes can be reserved.
  3. Special Environment Customization: If the equipment is to be installed in high-altitude (>2000m), high-salt-spray, heavy-pollution, or extreme-temperature areas, please provide detailed information at the time of ordering so that enhanced anti-corrosion or insulation design can be applied.

● Commercial & Project Information

  1. Basic Project Information: Provide your company name, project name, installation address, and expected delivery deadline.
  2. Contact Information: Provide the name and phone number of the technical contact person and the commercial liaison person, so that our engineering team can communicate with you promptly to confirm technical details.
  3. Spare Parts: If you have special spare parts requirements (e.g., spare fuses, reactive power compensation controllers, dedicated keys, etc.), please list the names and quantities together with your order.

 

Tip: The final quotation, technical parameters, and delivery schedule for specific products shall be subject to the technical agreement and commercial contract signed by both parties. Thank you for choosing our products!
