G11-H Epoxy Glass Tube Thermal Class 180°C High Temperature Insulation Application

Description

G11-H epoxy glass tube is a high-temperature, Class H (180 °C) insulating tube made from continuous E-glass filaments using a wet-winding process. The filaments are wound around a mandrel, impregnated with high-performance epoxy resin, and cured under controlled heat and pressure to produce seamless tubes with uniform strength. This process ensures excellent dielectric performance, low moisture uptake, and outstanding mechanical properties.

The laminate maintains at least 50% of its room-temperature flexural strength when exposed to transformer oil at 90 ± 2 °C, making it suitable for high-voltage and compact electrical insulation applications.

Features

• High mechanical strength: excellent flexural and tensile properties

• Low dielectric loss and stable electrical insulation

• Minimal moisture absorption for reliable performance in humid conditions

• Chemical and transformer oil resistance

• Maintains significant flexural strength under high-temperature oil exposure

• Seamless laminate construction for uniform strength and durability

• Customizable wall thickness and diameter for precise engineering applications

Applications

• Compact insulation components in electrical and electronic equipment

• Insulating structural parts for high-voltage power distribution systems

• Support and insulation in transformers, switchgear, and reactors

• Components exposed to transformer oil or humid operating environments

• Industrial electrical applications requiring high mechanical and thermal stability
