If you want to use electricity, you must have wires, and as long as there are wires, you must have connectors, even if you have a whole wire, but in the process of actually laying the wire, or because of the intermediate access device, or For other reasons, it will be cut. In this case, the joint is extremely important. The wire cannot be in contact with water. For some wires working in water, if you want to get good performance. It is also necessary to use a waterproof joint, because only its use can completely separate the power transmission from the water.
There are a lot of electricity requirements for working near or under water, such as lighthouses, boats, street lamps, etc., all of which must also use electricity, but at the same time as electricity, or it is near water, or In the case of rainwater, there will be water. Under such circumstances, if the joints appearing on the wires are waterproof, it will cause certain damage to the equipment. Even if it is not lost, it will not operate normally. Therefore, it is necessary to use waterproof joints. It can be used to ensure good work in electrical equipment with water or direct water.
It is also because of the importance of waterproofing, so when choosing a waterproof joint, we must pay attention to its regularity. Many people just think that it is very small, it is not particularly important, and as a result, it has caused a certain loss. Now this There are many types of joints, but there are not many real waterproofing. Some can only prevent watering, and some are inclined, even if water enters, let alone direct underwater power transmission. A good joint must be placed under a hundred meters of water and under water pressure, and there will be no water ingress. Only this can be used with confidence.
