How to waterproof a junction box

Release time:2023-10-17 11:09:11

Junction boxes need to be waterproofed mainly because moisture and humidity can have adverse effects on electrical components. If water and humidity enter the box, it may cause electrical short circuits, component corrosion and other problems, thus affecting the normal operation of the equipment. Especially outdoors or in humid environments, the effects of water and moisture are more significant.

The use of waterproofing measures can effectively prevent moisture and humidity from entering and protect internal electrical components from damage. During the design and manufacturing process, factors such as waterproof performance, dust resistance, and corrosion resistance need to be taken into consideration to ensure that it can work properly in harsh environments.

In some specific application scenarios, waterproof junction boxes play a crucial role. For example, in projects such as water supply/drainage pipe network monitoring and groundwater monitoring, the equipment installation site is often wet and prone to flooding. If the waterproofing effect is poor, it may cause equipment failures such as instruments and telemetry terminals (RTU). Therefore, waterproofing is an important measure to ensure the normal operation of these devices.

In short, waterproofing is crucial for junction box, which can effectively avoid the impact of water and humidity on internal electrical components and ensure the normal operation of the equipment. Especially in harsh environments, waterproofing is indispensable.

In terms of material selection, the box body materials mainly include ABS engineering plastics, polycarbonate (PC), PC/ABS, glass fiber reinforced polycarbonate, stainless steel, etc.

The price of ABS plastic is relatively low, but it can still meet the requirements of outdoor use. In addition, the price of a waterproof junction box is also related to the size and waterproof level. Generally, the larger the size, the higher the price, and the higher the waterproof rating, the more expensive the price. In order to ensure effective waterproofing, in addition to selecting appropriate materials and designing structures, strict quality inspection is also required. Generally speaking, the box needs to undergo a 72-hour pressure test to confirm that there is no leakage, deformation, etc.
