How to choose the right IP68 waterproof cast aluminum junction box

铸铝接线盒 How to choose the right IP68 waterproof cast aluminum junction box
1. Select the correct seal level
防水接线盒 Optional waterproof junction box , IP protection level is a very important factor. According to IEC-60529, the ** number of IP (Ingress protection) rating is the ability of the shell to resist the intrusion of solid particles, and the second number represents the shell's ability to protect against water droplets. 铸铝接线盒 IP等级全部达到IP67,这就意味着能够适应比较苛刻使用环境。 Tianshe waterproof cast aluminum junction box has an IP rating of IP67, which means that it can adapt to more severe use environments.
电缆防水接头 ,其防护等级应该比箱体高(市面上主流的防水电缆接头都能达到IP68的标准)。 The IP rating is only defined for the housing, but the equipment should also meet the corresponding requirements after installation. That is to say, if the waterproof junction box needs to be installed with a cable waterproof connector , its protection level should be higher than the cabinet (the mainstream on the market All waterproof cable connectors can meet the IP68 standard).
2. Choose the right size
Of course, the selection of the correct size of the waterproof box is based on the size of the existing components and the location of the device. However, we should also consider whether new components will be added in the future, and if so, whether his space is sufficient. Also note that the reference size provided by the junction box supplier is the external or internal dimensions. It should also be noted that the installable space is usually smaller than the internal dimensions provided.
3. Note that the standard configuration of the product includes those parts
Most manufacturers (especially domestic manufacturers) their product numbers do not reflect the inclusion of those standard accessories. Generally we can understand that a junction box contains the cover, the box body, the sealing strip and the cover screw. According to different needs, manufacturers will also be equipped with optional accessories such as fixed wall hanging corners, installation floor, cable joints. In order not to cause trouble afterwards, it is necessary to find out which are standard parts and which are optional accessories before ordering.
4. Equipment long-term working environment
Generally speaking, buy only the right ones and not the expensive ones. Waterproof junction boxes also vary greatly in price depending on the material. Before selecting the type, you should first determine whether the equipment will work indoors or outdoors for a long time. If it is the former, we recommend the relatively low-priced ABS waterproof junction box. ABS can fully meet the general needs of the indoor with its excellent comprehensive performance; It is an outdoor environment. It is better to use a polycarbonate waterproof junction box. It has better weather resistance, heat resistance, flame resistance, UV resistance, and aging resistance than ABS materials. Of course, the price is higher.
