Power Distribution Box

1. The power distribution box is mainly used for power distribution, control and protection of power equipment in industrial and civil buildings. It can reasonably distribute the upper - level power supply to multiple electrical equipment circuits, providing stable power for power equipment such as motors, water pumps, fans, and compressors.

2. By configuring components such as circuit breakers, contactors, and thermal relays, it can realize functions such as on - off control of circuits, overload protection, short - circuit protection, and phase - loss protection, ensuring the safe operation of electrical equipment.

3. In some large - scale projects, the power distribution box can also be combined with the PLC control system to realize automatic control and intelligently adjust power distribution according to the needs of the production process.

1. In terms of raw material selection, we always adhere to strict standards. The box of the power distribution box is made of high - quality cold - rolled steel plate or aluminum alloy. The cold - rolled steel plate is processed by special technology, with high strength and good toughness, which can resist high - strength mechanical impact and easily cope with collisions and挤压 in industrial environments.

2. The aluminum alloy material, with its excellent corrosion resistance, can remain stable and durable in harsh environments such as humidity, acid and alkali.

3. The surface of the distribution box is processed through multiple procedures. Phosphating is used as a primer to enhance adhesion, and electrostatic powder spraying forms a dense anti - rust layer, ensuring that it is not easy to rust or fade during long - term use.

4. The core electrical components inside the power distribution box have in - depth cooperation with international and domestic first - tier brands. From circuit breakers and contactors to fuses, each component has undergone strict screening and performance testing, and can still maintain stable operation under high current and high load conditions, providing a solid guarantee for the reliable performance of the distribution box.

1. The power distribution box has a shell made of pressed steel. The knife - switch type operating handle is integrated in the column area at the upper right of the front side of the box, which conforms to the ergonomic layout and is convenient for quickly switching the power on and off.

2. The door of the power distribution box can be installed with a digital display instrument, which can display electrical parameters such as current and voltage. There is a door in front of the distribution box. After the door is opened, all the equipment in the distribution box is exposed, which is convenient for maintenance.

3. This distribution box uses self - designed components, which have the characteristics of compact structure, convenient maintenance and flexible combination of line schemes.

4. This series of power distribution systems integrates multiple protection modules: the main circuit is equipped with air circuit breakers and high - breaking fuses to achieve short - circuit protection; the control unit is equipped with a contactor - thermal relay group to accurately manage the risk of motor overload; the anti - touch front panel can be installed with operation buttons and indicator lights.

• Temperature range: The normal operating temperature is - 15 °C to + 60 °C, and special design is required for extreme environments.
• Humidity requirement: Relative humidity ≤ 90% (at 25 °C), condensation should be avoided, and moisture - proof treatment is required in high humidity environments.
• Altitude: Generally applicable to altitude ≤ 2500 meters, and derating is required for higher altitudes.
• Protection level (IP): IP40 is selected for indoor dry environments, and IP55 or above is selected for outdoor or dusty and humid environments.
• Corrosion and explosion protection: Avoid corrosive gases, and explosion - proof design is required in explosive environments.
• Mechanical vibration: The installation location should be far away from strong vibration sources, and shock absorption measures should be taken if necessary.

If you have special requirements, you can negotiate with us, and we can customize according to your special environmental requirements.

1. In the packaging link, we use high - strength cartons with buffer materials such as pearl cotton and foam boards to provide multi - layer protection for the distribution box, ensuring that the product is protected from collision and extrusion during transportation. For large - scale distribution boxes, wooden frames will also be used for reinforced packaging to further improve the protection performance.

2. In terms of transportation, we have established long - term cooperation with many professional logistics companies. We can provide various transportation methods such as sea freight and air freight according to customer needs. We purchase cargo transportation insurance throughout the process and track logistics information in real time to ensure that products are delivered to customers safely and quickly.

Q: How to get the quotation of the power distribution box, and what do I need to provide?

A: If you need a quotation for the power distribution box, you need to inform us of the internal configuration, required quantity, rated voltage and current, material selection, overall dimensions, etc., and we will make a quotation according to your needs.

Q: What are the requirements for space and heat dissipation when installing the power distribution box?

A: Space: Reserve ≥ 50cm heat dissipation distance around, and avoid stacking debris on the top.

Heat dissipation: In high - temperature environments, it is necessary to install heat dissipation fans or ventilation holes (provided that the IP level allows).

Q: What items need to be checked in the daily maintenance of the power distribution box?

A: Monthly inspection: tightness of terminal blocks, temperature rise, peculiar smell, and state of circuit breakers.

Annual inspection: insulation resistance (≥ 1MΩ), grounding performance, and component aging.

Q: What should be paid attention to when using the power distribution box in plateau areas (altitude > 2000 meters)?

A: The thin air leads to poor heat dissipation and reduced insulation performance of the distribution box. It is necessary to use it with derating or select a plateau - specific model.

Q: How to do a good job in moisture - proof of the power distribution box in a humid environment?

A: You can choose a stainless steel shell, select an IP65 or above protection level, install an anti - condensation heater or dehumidification module in the box, and check the sealing strip regularly.
