Customize XL-21 Power Distribution Cabinets with Inner Doors for China Electric in Hebei

Core Requirement Analysis

1. **Features of XL-21 Power Distribution Cabinets**

As a mainstream product in the low-voltage power distribution system, the XL-21 type has the following characteristics:

- Standard Configuration: Cold-rolled steel plate cabinet body (thickness 0.8-2.0mm), IP30 protection level, rated current 630A, short-circuit withstand current 15-36kA.

- Customization Flexibility: Supports function expansion such as dual-power supply switching, soft start control, intelligent monitoring, etc.

- Inner Door Design: Usually adopts a detachable cold-rolled steel plate structure, and an insulating layer or observation window can be installed to improve safety and maintenance convenience.

2. **Industrial Advantages of Hebei Region**

Hebei Province has formed a complete industrial chain in the field of electrical equipment manufacturing. Many professional manufacturers are gathered in Baoding, such as:

- **China Electric**: Provides customization services for XL-21 power distribution cabinets, and supports non-standard design and intelligent control integration.

Focuses on high and low voltage complete sets of equipment, and can configure inner doors and special protection functions according to requirements.

Manufactures high and low voltage power distribution cabinets and has the ability of cabinet processing and electrical component assembly.

 II. Customization Process and Technical Key Points

2. **Customization Process Suggestions**

- **Requirement Confirmation**: Clarify the voltage level (380V/220V), rated current (225A-630A), installation environment (indoor/outdoor) and special functions (such as dual-power supply switching).

- **Supplier Selection**: Give priority to contacting local enterprises (such as Shijiazhuang Delan Electric and Hebei Liangkong Intelligence), and you can obtain quotations through platforms such as China Suppliers Network and Jiuzheng Building Materials Network.

- **Drawing Review**: Require the supplier to provide a 3D design drawing, and focus on confirming whether the spacing between the inner door and the busbar and the circuit breaker complies with the GB7251.1 standard.

- **Production Cycle**: The production cycle for regular orders is 15-30 days, and the customization with special functions needs to be extended to 45 days.

III. Recommendations of Local Suppliers

IV. Cost and Delivery Reference

1. **Price Range**

- Standard XL-21 Power Distribution Cabinet (excluding inner door): 5,000-8,000 yuan per unit.

- Customization with inner door: An additional 1,500-3,000 yuan per unit (depending on the material and function).

- Intelligent control upgrade: The PLC module is about 2,000-5,000 yuan per set, and the remote monitoring system is calculated separately.

2. **Delivery Cycle**

- Regular orders: 15-20 days (in Shijiazhuang and Baoding regions).

- Complex customization (such as IP54 protection): 30-45 days.

- Logistics cost: About 200-500 yuan per unit within Hebei Province, and cross-provincial transportation needs to be calculated separately.

V. Risk Control Suggestions

1. **Qualification Verification**

- Require the supplier to provide ISO9001 certification, 3C certification and type test reports (such as TUV, CE).

- Conduct on-site inspections of the production workshop, and focus on the welding process, spraying quality and component brands (such as Schneider, ABB).

2. **Contract Terms**

- Clarify the warranty period (usually 1-2 years) and the after-sales service response time (within 24 hours).

- Agree on the acceptance standards (such as GB7251.1-2013) and liability for breach of contract (such as compensation for delayed delivery).

3. **Transportation and Installation**

- It is recommended to use wooden box packaging, and the cabinet body needs to be fixed during transportation to prevent shaking.

- Professional electricians are required to conduct grounding tests and withstand voltage tests during installation to ensure safe operation.

If you need further assistance in screening suppliers or reviewing technical solutions, you can provide more detailed technical parameters (such as the material and size requirements of the inner door), and I will continue to provide support for you.
