SHS prepreg is an insulating material formed by impregnating a polyimide film and a polysulfone fiber nonwoven fabric impregnated with class H heat-resistance epoxy resin. It is mainly used for interlayer insulation and ground insulation of H-class dry-type transformers.

Core Characteristics

Curing Conditions: Cures at 120°C for 5 hours or 150°C for 3 hours. The process produces no low-molecular volatiles and exhibits minimal shrinkage.

Application: Used as interlayer and ground insulation for Class H dry-type transformers.

Features of SHS prepreg:

1. Superior Electrical Insulation

Offers exceptional dielectric strength to effectively prevent current leakage and short circuits, ensuring operational safety of electrical equipment.

2. High-Temperature Resilience

Rated for Class H (180°C) temperatures, it maintains stable performance and structural integrity in demanding high-heat environments.

3. High Mechanical Strength

Possesses robust mechanical properties to withstand external stresses, protecting the insulation layer from damage and ensuring long-term reliability.

4. Excellent Adhesion

Bonds securely to various substrates, ensuring a seamless fit on equipment surfaces for superior insulation and void-free performance.
