How to Choose the Right Distribution Cabinet? — A Complete Selection Guide Česká republika

In power systems, distribution cabinets are critical for ensuring efficient power distribution. As a professional manufacturer of distribution cabinets, we often receive inquiries about choosing the right product. Today, we’ll provide a comprehensive guide to help you make an informed decision.

1. What is a Distribution Cabinet?

A distribution cabinet is a device used for electrical power distribution and control, commonly utilized in industrial, commercial, and residential settings. Its primary functions include:

Power distribution

Circuit protection

Equipment control

Based on voltage levels, distribution cabinets are typically categorized as:

Low-voltage distribution cabinets (

High-voltage distribution cabinets (>1000V)

2. Key Factors in Selecting a Distribution Cabinet

(1) Application Scenarios

Different scenarios require specific features:

Industrial environments: Designed for high-power equipment, typically using models like GCS or GGD.

Commercial buildings: Focus on aesthetics and energy efficiency.

Outdoor environments: Require high protection ratings (e.g., IP65) to guard against dust and water.

(2) Electrical Parameters

Ensure the cabinet meets your electrical system’s requirements:

Rated voltage (V): Match the system, such as 400V or 12kV.

Rated current (A): Calculate the required current based on the load power.

Short-circuit current (kA): Choose products with sufficient short-circuit strength to ensure safety.

(3) Functional Requirements

The functional modules vary based on usage needs, such as:

Control circuits

Protection devices

Power metering

(4) International Certifications

Ensure the cabinet complies with local regulations and standards, such as ISO9001 or CE certifications.

3. Common Types of Distribution Cabinets

Here’s a summary of common cabinet types, their features, and application scenarios:

Model	Applicable Voltage	Applications	Features
GGD	Low-voltage	Factories, buildings	Stable performance, modular design
GCS	Low-voltage	Motor control centers	Suitable for high-current scenarios
KYN28	High-voltage	Power utilities, substations	Reliable, easy to maintain
XL-21	Low-voltage	Small projects	Cost-effective, compact size
