Low-voltage switchgear series

Normal Service Environment

Ambient Temperature: -5°C ~ +40°C (the average temperature within 24 hours shall not exceed +35°C)

Altitude: ≤ 2000 meters

Relative Humidity: Not exceeding 50% at the maximum temperature of +40°C; higher relative humidity is allowed at lower temperatures (e.g., up to 90% at +20°C). Condensation due to temperature variations must be taken into consideration.

Installation Environment: Locations without severe vibration and shock, and free from electrical and chemical gases that may corrode metals or damage insulation.

Functions & Features

Comprehensive Solutions:

Provides various structural forms such as fixed-type and drawer-type, with flexible circuit configurations to meet the requirements of various main wiring schemes.

Safe and Reliable: Safe and Reliable:

The cabinet body is manufactured from high-strength steel, featuring a complete set of "Five-Prevention" interlock functions (preventing incorrect circuit breaker switching, preventing load-break disconnector operation, preventing live grounding wire connection, preventing energization with grounding wires, and preventing entry into live compartments), effectively preventing misoperation. Each functional compartment (busbar compartment, functional unit compartment, cable compartment) is isolated from the others to ensure operational and maintenance safety.

High Breaking Capacity: High Breaking Capacity:

Equipped with high-performance circuit breakers featuring powerful short-circuit breaking capacity, capable of rapidly interrupting fault currents and protecting downstream equipment.

Easy Maintenance:

The functional units of drawer-type cabinets offer excellent interchangeability. In the event of a fault, spare drawers can be quickly replaced, significantly reducing downtime and improving power supply continuity.

Intelligent Monitoring:

Can be integrated with intelligent instruments, communication modules, etc., to achieve real-time monitoring of electrical parameters such as voltage, current, power, and energy, as well as remote communication, facilitating intelligent distribution management.

Main Series Configuration & Application Comparison

Information Required for Inquiry or Order Placement

Please provide the following accurate information when making an inquiry or placing an order, so that we can perform technical calculations and schedule production:

Project Overview:

Project name, installation location, service environment (e.g., altitude, maximum/minimum temperature, relative humidity, presence of corrosive gases or severe vibration, etc.).

Product Model & Specifications:

Clearly specify the required low-voltage cabinet model, rated voltage (V AC), rated current (A), and rated frequency (Hz).

Key Technical Parameters & Configuration Requirements

Main Busbar Specifications: 

Specify the rated current, material (copper bar/aluminum bar), and arrangement (horizontal/vertical) of the main busbar.

Incoming/Outgoing Line Method: 

Specify whether cable entry/exit is from the top or bottom, or if a busbar bridge connection is required.

Reactive Power Compensation: Reactive Power Compensation:

Specify whether a capacitor compensation cabinet is required, as well as the compensation capacity, switching method (contactor / thyristor), and controller requirements.

Instruments & Protection: Instruments & Protection:

Specify the instruments required for each circuit (ammeter, voltmeter, multifunction power meter, etc.) and the configuration of relay protection devices (overcurrent, instantaneous trip, leakage protection, etc.).

Communication Requirements:

Specify the required communication interface (e.g., RS485) and communication protocol (e.g., Modbus-RTU) for integration into the host computer monitoring system.

Appearance & Color: 

Specify cabinet dimensions (H × W × D), enclosure material (cold-rolled steel plate / aluminum-zinc coated plate), and color (e.g., RAL 7035).

Ordering Process & Precautions

Provide System Diagrams:

Please provide detailed primary system diagrams and secondary schematic diagrams, which form the basis for quotation and production.

Confirm Technical Agreement:

For projects with special requirements, both parties shall sign a technical agreement to clarify all technical details.

Drawing Confirmation:

Prior to production, we will provide cabinet arrangement drawings and foundation drawings for your confirmation. Please review them carefully.

Site Conditions:

Please ensure that the foundation, cable trenches, etc. at the installation site comply with the drawing requirements and that sufficient space is reserved for operation and maintenance.
