Fiberglass Sleeve – High-Temperature Electrical Insulation for Cables and Components

Fiberglass Sleeves are woven tubular insulation products made from braided or knitted glass fiber yarns. Known for their exceptional thermal resistance, electrical insulation, and mechanical durability, these sleeves are widely used in industrial and electrical applications where wires, cables, and components need protection against heat, abrasion, and electrical stress.

These sleeves can be coated with various materials—such as silicone, acrylic, or polyurethane—to enhance their performance characteristics, including flame resistance, flexibility, or moisture repellency. Depending on the coating and glass grade used, fiberglass sleeves can operate in temperature ranges from -60°C to over 250°C, making them ideal for harsh environments.

Key Features:

• Excellent Thermal Resistance: Operates reliably in high-temperature environments up to 550°C (uncoated) or 200–250°C (coated).

• Superior Electrical Insulation: Offers high dielectric strength, making it suitable for high-voltage applications.

• Mechanical Protection: Shields cables and hoses from cuts, abrasion, and impact.

• Flexible & Lightweight: Easily conforms to bends and curves in wiring setups.

• Flame Retardant Options: Silicone or acrylic coatings improve fire resistance and self-extinguishing properties.

• Chemical & Moisture Resistance: Withstands oils, solvents, and humid conditions.

Types of Fiberglass Sleeves:

1. Uncoated Fiberglass Sleeve – Basic thermal and electrical insulation, used in non-exposed environments.

2. Silicone Coated Fiberglass Sleeve – Offers excellent heat, flame, and moisture resistance.

3. Acrylic or Polyurethane Coated Sleeve – Enhanced mechanical strength and environmental protection.

4. Expandable (Braided) Sleeves – Flexible for variable cable diameters.

5. Heat Shrink Fiberglass Sleeves – Shrinkable for a tight, customized fit.

Applications:

• Electric Motors and Transformers: Insulating coil leads and terminal connections.

• Automotive and Aerospace Wiring: Protects cables from heat and abrasion in engines and avionics.

• Power Electronics: Covers and insulates high-voltage connections and busbars.

• Industrial Furnaces and Equipment: Safeguards sensors, thermocouples, and wiring in high-heat zones.

• Consumer Electronics & Appliances: Insulation and bundling of internal wiring.
