Fortify Your Electrical Safety with Custom FRP Insulation Sleeves

High-Performance, Fire-Resistant Insulation Solutions for Busbars, Electrical Enclosures & Switchgear

In the heart of electrical connection and power distribution systems, the safety and reliability of busbars are paramount to the stable operation of the entire electrical network. Exposed conductors not only pose an electrocution risk but can also lead to severe failures due to arcing, dust, or condensation.

Understanding your critical need for superior electrical encapsulation, we introduce our 【Custom FRP Insulation Sleeves】—the ultimate protective solution engineered for the most demanding electrical environments.

Why Choose Our FRP Insulation Sleeves?

1. Superior Fire Resistance (FR) Performance

· Manufactured from high-quality Glass Fiber Reinforced Epoxy (FRP) material, achieving the highest UL94 V-0 flame retardancy rating.

· Effectively prevents flame propagation under high temperatures or short-circuit conditions, providing vital response time for critical facilities and serving as the first line of defense for personnel and equipment safety.

2. Exceptional Mechanical & Electrical Strength

· High Mechanical Strength: Impact-resistant and wear-proof, providing reliable physical protection for busbars in confined installation spaces or high-vibration environments.

· Excellent Insulation Properties: Delivers high dielectric strength and extended creepage distance, preventing phase-to-phase and phase-to-ground faults, ensuring stable performance in high-voltage applications.

3. Precision Customization for Perfect Fit

· Full Customization to Drawings: We offer comprehensive, precise customization—from diameter, wall thickness, and length to special features (e.g., connector windows, mounting holes).

· Perfect Fit Design: Whether for round, rectangular, or irregularly shaped busbars, our sleeves ensure a tight, gap-free enclosure, maximizing insulation effectiveness while optimizing cabinet space.

4. Outstanding Environmental Durability

· Moisture & Corrosion Resistance: Resistant to humidity, mold, and most chemical agents, making it ideal for harsh environments such as offshore platforms, chemical plants, and outdoor substations.

· High-Temperature & Aging Resistance: Wide operating temperature range with long-term stability, offering a service life far exceeding that of standard PVC or heat-shrink tubing.

Core Application Scenarios

· ✅ Insulation for busbar systems in medium/high-voltage switchgear & distribution panels

· ✅ Electrical encapsulation in data centers, power plants & substations

· ✅ Power distribution systems in rail transit, marine electrical & renewable energy (wind, solar) applications

· ✅ Safe isolation for dense busbars in industrial automation equipment
