Waterproof Junction Box Materials Selection Guide

1、 Before learning, one must know
A waterproof junction box is a device used for electrical connections, which protects the interface of two or less cables to achieve waterproofing and corrosion resistance. It is widely used in outdoor environments, damp places, and other electrical connections. There are various types of materials for junction boxes, and we will explain them one by one below.
2、 Material of waterproof junction box

1. Metal material

Metal junction boxes are protected internally with materials such as plastic or silicone. This type of junction box is made of metal material, so its structure is relatively hard, resistant to heavy pressure and not easy to wear, and also has good anti-corrosion and shock resistance.
2. Aluminum alloy material

Aluminum alloy is a special material for making waterproof junction boxes. Aluminum alloy has excellent thermal conductivity and weather resistance, which can effectively prevent electrical appliances from being damaged from humid environments.
3. Plastic material

Plastic material is currently the most widely used type of material. Most waterproof junction boxes are made of plastic materials such as polypropylene or polycarbonate, which have low manufacturing costs and long service life. Moreover, a major advantage of plastic waterproof junction boxes is their low corrosion during use, as well as their good mechanical strength and insulation.
3、 Applicable scenarios for different materials
The adaptability of waterproof junction boxes made of different materials varies, and the specific use needs to be selected according to the specific situation:
Metal waterproof junction boxes are suitable for environments with long service life requirements and can withstand certain pressure and friction.
The waterproof junction box made of aluminum alloy material is suitable for outdoor long-term use places, such as seaside, mining, etc.
Plastic waterproof junction boxes are suitable for short-term use in areas with high rainfall and low atmospheric corrosion.
4、 Summary
As a commonly used electrical connector, waterproof junction boxes have a variety of materials. Overall, metal waterproof junction boxes are suitable for environments with a long service life, aluminum alloy waterproof junction boxes are suitable for outdoor long-term use, and plastic waterproof junction boxes are suitable for short-term use, areas with high rainfall, and low atmospheric corrosion.
