A waterproof junction box is a device specially designed to prevent the wiring parts of electrical equipment from being damaged by moisture, moisture and other environmental factors. They are usually installed in buildings, bridges, roads, tunnels and other places to ensure the normal operation and safety of electrical equipment. There are many types and specifications of waterproof junction boxes. Here are some common types and specifications:

1. Classification by material:

(1) Plastic waterproof junction box: Plastic junction box is made of high-strength engineering plastics and has good waterproof performance, corrosion resistance and insulation performance. They are commonly used in indoor and outdoor low voltage electrical equipment.

(2) Metal waterproof junction box: Metal junction box is made of aluminum alloy or stainless steel and has high strength and weather resistance. They are commonly used in outdoor high-voltage electrical equipment and electrical equipment in harsh environments.

2. Classification by installation method:

(1) Wall-mounted waterproof junction box: Wall-mounted junction box is installed directly on the wall or other structural surface and is suitable for indoor and outdoor electrical equipment.

(2) Ground-type waterproof junction box: Ground-type junction box is installed on the ground and is suitable for underground electrical equipment and electrical equipment that require frequent inspection and maintenance.

(3) Embedded waterproof junction box: Embedded waterproof junction box is embedded in concrete or other materials and is suitable for large electrical equipment and electrical equipment that needs to be hidden.

3. Classification by function:

(1) Single-pass waterproof junction box: The single-pass waterproof junction box has only one inlet and one outlet, and is suitable for electrical equipment in a single circuit.

(2) Two-way waterproof junction box: The two-way waterproof junction box has two wire inlets and one wire outlet, and is suitable for electrical equipment in two circuits.

(3) Three-way waterproof junction box: The three-way waterproof junction box has three wire inlets and one or two wire outlets, and is suitable for electrical equipment with three circuits.

4. Classification according to protection level:

(1) IP65 waterproof junction box: IP65 waterproof junction box has good dustproof and waterproof performance and is suitable for outdoor electrical equipment.

(2) IP67 waterproof junction box: IP67 waterproof junction box has good dustproof, waterproof and anti-corrosion properties, and is suitable for electrical equipment in harsh environments.

5. Classification according to specifications and sizes:

There are many specifications and sizes of waterproof junction boxes, and the appropriate specifications and sizes can be selected according to the needs of electrical equipment. Common specifications and sizes include: 50x50mm, 70x70mm, 100x100mm, 150x150mm, etc.

In short, there are many types and specifications of waterproof junction boxes, and the appropriate waterproof junction box can be selected according to the needs of the electrical equipment and the use environment. When selecting a waterproof junction box, you should pay attention to factors such as its material, installation method, function, protection level, and size to ensure the normal operation and safety of electrical equipment.
