APG Injection Epoxy for Current Transformers - High Insulation & Flame Retardant

Brief Introduction

LE-8214 is a modified BPA-type epoxy resin designed for enhanced performance.

LH-8214 is a liquid modified carboxylic acid anhydride curing agent.

APG Injection Epoxy for Current Transformers - High Insulation & Flame Retardant

Engineered for current transformers, this APG injection epoxy offers superior dielectric strength and flame retardancy. Its low-shrinkage formula ensures dense encapsulation via automatic pressure gelation, blocking moisture and external interference. Ideal for high-voltage systems, it delivers long-lasting insulation stability from -40°C to 155°C.

Applications

• Suitable for electrical insulation in medium and high voltage applications.
• Ideal for dry-type transformers, 10-66 kV current transformers, voltage transformers, and related components.

Processing Methods

• Conventional Gravity Casting Process under vacuum.
• The production process can be tailored to meet the client's existing manufacturing techniques.

Properties

• This system consists of a two-component saturated cyclic epoxy resin without pre-mixed fillers, remaining in liquid form at room temperature.
• Features low curing shrinkage, excellent dimensional stability, superior processing capabilities, and outstanding mechanical and electrical properties.

Formulation

Professional-Grade Insulation Assurance

This APG injection epoxy resin raw material is specifically developed for current transformers, boasting excellent high dielectric strength and flame-retardant performance, meeting the stringent safety standards of electrical equipment. Leveraging the APG (Automatic Pressure Gelation) injection process, it achieves low shrinkage rates and high density, ensuring tight encapsulation of internal components within the transformer. This effectively isolates moisture and external interference, significantly enhancing the long-term operational stability and service life of the equipment, making it a reliable choice for insulation protection in power systems.
