Product description
Parameters

SHS prepreg is a flexible composite material made of polyimide film coated with H-grade adhesive and polyester fiber non-woven fabric, and then impregnated with epoxy prepreg semi-cured resin to become a reliable thermal adhesive material. With excellent dielectric properties, bonding properties and heat resistance, it is an ideal interlayer insulation material and ground insulation material for H-class dry-type transformers. The heat resistance grade is H grade (180℃).

 

Product Features

With high mechanical strength and excellent electrical properties, it is suitable for high-strength insulation systems.

Excellent heat resistance, can be used as H-class insulation.

The material has good flexibility, the resin and the SHS matrix have strong adhesion, and does not drop powder. It is especially suitable for use in the interlayer insulation of dry-type transformers. The soluble resin content is large, and the product can form a strong insulating layer after being wound on the conductor and thermally cured, and the peeling strength is very high.

The storage period is long, the product molding process is simple, and the logo color is yellow.

The low volatile content ensures low partial discharge of the product.

 

Packaging and storage

The products are sealed with reinforced plastic film and packed into cartons. Each box weighs no more than 60Kg. Stored upright and stored in a ventilated and dry room temperature environment. Fire, pressure and sun protection should be used during transportation and storage. The storage period is 12 months at room temperature.

 

Product Application

It is suitable for H-class dry-type transformer coil interlayer insulation, end seal insulation and ground insulation, and motor turn-to-turn insulation.
