electrical insulating material

Characteristics and uses:

The product is made of cotton yarn. It has a certain tensile strength and insulation property. It has high mechanical properties, elastic and extensibility with good dielectric properties. The surface is smooth.

According to the technology, it is divided into plain belt and twill tape. It is widely used in motor and electrical appliance. It has high mechanical properties, elasticity and elongation, and has good dielectric properties. The surface is smooth. The cleanliness is high. The permeability is good. It has enough mechanical strength under a certain thickness. Moderate extension

White cloth belt product technical index:

The material is divided into pure cotton belt and polyester belt. According to the process, the strip and twill belt are divided. The nominal width (mm): 15, 20, 25, 30 are used for the winding insulation of the motor and transformer coil.
