The types of electrical metal bushings are mainly based on factors such as material, specifications, wall thickness and use environment. Different types of electrical metal bushings are suitable for different electrical installation requirements, and choosing the appropriate model can ensure the safety and stability of the electrical system. The following are some common ways to distinguish between them to help you better understand and choose the right electrical metal bushing:

1. Material distinction

Galvanized steel pipe: This pipe has strong corrosion resistance and is suitable for humid or highly corrosive environments. Liansu's electrical metal bushing is made of high-quality galvanized steel, which can ensure that the pipeline maintains good durability and corrosion resistance in long-term use.

Stainless steel pipe: stronger corrosion resistance, suitable for more harsh environments, such as chemical plants, food processing and other fields.

Aluminum pipe: Aluminum pipe is lighter than steel pipe, is often used in places that do not require extremely high mechanical strength, and has good corrosion resistance.

2. Specification distinction

The specification of the electrical metal bushing is usually calibrated by the outer diameter and the wall thickness. The common outer diameter specifications are 20mm, 25mm, 32mm, 40mm, 50mm, etc. The difference in wall thickness determines the strength of the pipeline and the applicable scenario. Liansu electrical metal bushing has a variety of specifications, which can meet the electrical installation requirements of different places.

3. Wall thickness and strength grade

The wall thickness of electrical metal bushings can be divided into light, medium and heavy. The pipeline products provided by Liansu include different strength grades, which can meet various needs from residential to industrial facilities and ensure long-term stable operation.

4. Surface treatment

Galvanized pipe: Liansu's electrical metal casing is galvanized to provide excellent corrosion resistance, especially suitable for humid and corrosive environments.

Black tube: generally used in a relatively dry environment, low cost.
