FXBW4-66/100 66kV Suspended Insulator

Name: FXBW4-66/100 66kV Suspended Insulator
Brand: Guangdong Yufeng Industries Co., Ltd.
Availability: InStock
Rating: 4.4 (1 reviews)

The crimping technology of the mandrel and the end fittings is the most critical technology of the suspension composite insulator. The quality of the crimping determines the mechanical properties of the product and directly determines the performance of the product. It is the key to measure the production of the suspension composite insulator. One of the most important indicators of the technical level of the manufacturer. Therefore, making the crimping process well and stabilizing is the first technical issue to be considered in this project.

Principles of FXBW4-66/100 66kV Suspended Insulator Crimping

The principle of crimping is that after inserting the mandrel into the inner hole of the fitting, the crimping machine is used to squeeze the fittings centripetally at eight points through the crimping die, so that the fittings and the mandrel are plastically deformed, and static friction is generated when the tension is applied to achieve mechanical connection.

The size and material of the mandrel and fittings have a great influence on the crimping quality. If the hardness and modulus of elasticity of the mandrel and fittings are too large, it is easy to press through or even break the mandrel; if the hardness and modulus of elasticity of the mandrel and fittings are too If the gap between the mandrel and the fittings is too large, there will be underpressure and the crimping strength will not be enough.
