Waterproof cable gland can be applied to environments with water, providing safe and reliable connector joints for junction boxes. For example, LED street lights, lighthouses, cruise ships, industrial equipment, sprinkler trucks, etc., all require the use of waterproof cable gland.

At present, the main evaluation standard for the waterproof performance of waterproof connectors is based on the IP waterproof grade standard. The waterproof performance of the waterproof cable gland mainly depends on the last two digits XX of IPXX. The first digit X ranges from 0 to 6, with a high level of 6; The second digit ranges from 0 to 8, with a maximum level of 8; Therefore, the highest waterproof level of the waterproof joint is IP68.

Waterproof cable gland are generally used in conjunction with waterproof junction boxes. These types of junction boxes are generally called cable gland waterproof boxes or terminal waterproof boxes. Depending on the number of openings, we also have waterproof boxes with one in, one out, and one in, two out to one in, multiple out. These include the following considerations:

1. Waterproof cable gland are usually installed on the wall of a plastic waterproof box, so the requirement for drilling holes is to meet the external thread size of the cable gland.

2. Consider wiring and drilling.  At least one in and one out, which involves at least two waterproof cable gland and two drilling on the box wall, so it is important to clarify the size and location of the drilling, as well as the corresponding waterproof cable gland size.

3. No matter the terminal in the junction box or other electrical components, they should be connected through waterproof connectors to ensure waterproof performance.
