When it comes to premium-grade insulation products, Twinkle Industries stands out as a trusted manufacturer delivering high-quality GPO laces designed to meet modern industrial standards.

What Are GPO Laces?

GPO (Glass Polyester Overbraided) laces are high-temperature insulating lacing cords manufactured using braided glass fiber yarn coated with polyester or other specialized resins. These laces are engineered to provide:

  • Excellent mechanical strength

  • High dielectric properties

  • Thermal resistance

  • Flame retardancy

  • Long service life

They are primarily used for tying and securing coil windings in motors, generators, and transformers where high heat and electrical stress are involved.

Key Features of GPO Laces

1. High Temperature Resistance

GPO laces can withstand elevated operating temperatures without losing structural integrity, making them ideal for heavy electrical machinery.

2. Superior Electrical Insulation

Their glass fiber construction ensures excellent dielectric strength, protecting equipment from electrical leakage and short circuits.

3. Strong Mechanical Binding

These laces provide tight knot strength and abrasion resistance, ensuring coil windings remain intact even under vibration.

4. Flame Retardant Properties

Safety is critical in electrical systems. GPO laces are designed to resist flame propagation.

5. Chemical & Moisture Resistance

They perform reliably even in humid or chemically exposed environments.

Applications of GPO Laces

GPO laces are widely used across multiple electrical and industrial sectors:

  • Motor coil lacing

  • Transformer winding insulation
