We Are Utility Pole Supplies
Our composite long rod insulators feature hydrophobic silicone housings and GFRP cores, engineered for lightweight performance, pollution resistance and ease of installation. Ideal for overhead line retrofits, catenary systems, railway electrification and substation applications.
Typical specifications
- Lengths: 300mm — 3000mm+ (customizable)
- Rated voltage: 24kV — 220kV (tailored to project)
- Mechanical performance: bending & tensile strengths validated by testing (contact for data)
- Fittings: forged or cast end fittings with corrosion protection options
Technical benefits
- Hydrophobic housing reduces pollution flashover and speeds recovery
- Lightweight design reduces tower loading and installation costs
- Retrofit-friendly end fittings compatible with legacy systems
Quality assurance
Comprehensive testing: tracking & erosion, UV ageing, mechanical load and hydrophobicity recovery. Full test reports available for project review.
Customization & samples
OEM and project-specific customization supported. Sample delivery and third-party test coordination available. Provide voltage, length and mechanical load in your inquiry.
