Welcome to Know About G10 Insulation Sleeves
G10 insulation sleeves are made from continuous alkali-free glass fibre yarn as reinforcement, impregnated with epoxy resin, and then cured under high temperature and pressure. Winding is the primary manufacturing method for the sleeves, offering the best performance.
Two Key Materials
The G10 insulation sleeves are made from two key materials, which provide many benefits. They have characteristics of insulation, corrosion resistance and wear resistance.
Glass fiber yarn
Provides high tensile strength and stiffness.
Epoxy Resin
It serves as a base material, bonding the fibres together, transmitting and distributing forces, and providing corrosion resistance and electrical insulation.
Why Use G10 Insulation Sleeves?
We use G10 insulation sleeves because they offer many benefits.
Good Electrical Insulation
Stops the currents: Prevents unwanted electrical flow between connected parts.
High Dielectric: Withstands high voltage without breaking down.
Isolates Fasteners: Keeps metal bolts from completing an electrical circuit.
Excellent Thermal Protection
Blocks Heat: Acts as a barrier against high temperatures.
Cryogenic Stability: Maintains structural strength in extreme cold.
Prevents Transfer: Keeps heat from travelling through structural joints.
Good Corrosion Prevention
Galvanic Isolation: Separates dissimilar metals like steel and copper.
Stops Electrolysis: Breaks the electrical path that causes metal decay.
Chemical Resistance: Resists damage from acids, oils, and solvents.
Good Mechanical Strength
High Tensile: Endures heavy crushing and tightening forces.
Zero Creep: Does not deform or shrink under constant pressure.
Moisture-proof: Absorbs almost no water, keeping its shape.
Applications
G10 insulation sleeves are used in various applications, including bolt protection, insulation, chemicals, military, medicine, and electricity.
