Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of waterproof distribution boxes, it is recommended to prioritize checking the protection level (such as IP65 or higher) and material corrosion resistance to ensure long-term stable operation in outdoor or humid environments.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers can usually provide technical solutions that are more suitable for industrial scenarios.
  • In highly corrosive scenarios such as chemical engineering and ports, extra attention should be paid to the sealing performance of waterproof distribution boxes and the moisture-proof design of internal components to avoid equipment failures caused by environmental factors.
  • If purchasing for temporary power supply on construction sites, it is recommended to choose a lightweight waterproof distribution box with a quick installation structure, and evaluate the reliability of its product's practical application cases based on the supplier's industry performance.

Knowledge Base

Q

The selection of protection standards for waterproof and dustproof distribution boxes requires comprehensive consideration of multiple factors. Firstly, it should be determined based on the usage environment. If in a general indoor environment, a lower protection level can be selected, such as IP30, which can prevent solid foreign objects with a diameter greater than 2.5mm from entering and protect against a small amount of splashing water. If the distribution box is installed outdoors in a place with some dust but little water splashing, IP54

Q

Enamel steel plate distribution boxes have excellent waterproof performance, mainly due to their various characteristics and designs. Firstly, the enamel steel plate itself has a tight material, a smooth surface, and is not easily penetrated. Water molecules are difficult to easily penetrate the enamel layer and enter the interior of the distribution box, effectively preventing water from entering. Its production process is exquisite, ensuring good sealing under various environmental conditions

Q

Waterproof distribution box is a type of power distribution box designed specifically for outdoor and humid environments. Its main functions and features are as follows: Basic concept: A waterproof distribution box is an electrical distribution box that is made by using special materials and processes on the basis of traditional distribution boxes, and has characteristics such as waterproof, moisture-proof, and dustproof.
