About Epoxy Glass Fiber Collar Bush

What is an Epoxy Glass Fiber Collar Bush?

An Epoxy Glass Fiber Collar Bush is a cylindrical insulating component with a flange or collar, made from epoxy resin-impregnated glass fiber (e.g., G10, G11, FR4). It is widely used for electrical insulation, mechanical spacing, and load distribution in high-voltage and high-temperature environments.

Key Features:

Excellent electrical insulation
High thermal resistance (up to 180220C, depending on the grade)
High mechanical strength and rigidity
Moisture and chemical resistance
Dimensional stability under load

Technical Specifications (Typical):

Parameter	Value / Range
Material	Epoxy Resin + Glass Fiber (G10/G11/FR4)
Outer Diameter (OD)	Custom (e.g., 10 mm 100 mm+)
Inner Diameter (ID)	Custom
Collar Thickness	2 mm 10 mm
Total Length	Custom
Dielectric Strength	10 kV/mm
Temperature Range	-40C to +220C
Flame Retardancy	UL94-V0 (for FR4)

Common Applications:

Industry	Application
Electrical	Bushing in switchgear, transformers
Motors & Generators	Shaft insulation, spacer bushes
Industrial	Mounting support in control panels
Automotive	EV components, thermal barrier bushings
Aerospace	Lightweight insulator for high-load areas
