FAQ

 

   FAQ:

1. What is a Silicone Rubber Suspension Insulator?
A Silicone Rubber Suspension Insulator is a type of composite (non-ceramic) insulator used in high-voltage overhead transmission and distribution lines. It consists of a fiberglass reinforced polymer (FRP) core rod for mechanical strength, surrounded by silicone rubber housing and sheds for electrical insulation and environmental protection. It is lighter and offers superior pollution performance compared to traditional porcelain or glass insulators.

2. What are the key advantages over porcelain/glass insulators?
Lightweight: 70-90% lighter, reducing tower load and installation cost.

Superior Hydrophobicity: Silicone rubber surface repels water, preventing continuous water films and reducing leakage current, especially in polluted or coastal areas.

High Mechanical Strength: Higher strength-to-weight ratio.

Vandalism & Impact Resistance: Does not shatter like porcelain/glass.

Easier Handling & Installation: Due to lighter weight.

Excellent Anti-Flashover Performance: In contaminated conditions.

3. What voltage classes do you cover?
We manufacture insulators for a complete range of applications:

Distribution Class: 11kV, 33kV, 66kV.

Sub-Transmission: 69kV, 115kV, 138kV.

High Voltage Transmission: 220kV, 275kV, 330kV.

Extra & Ultra-High Voltage (EHV/UHV): 500kV, 750kV, 1000kV+.

DC Transmission Lines: ±400kV, ±500kV, ±800kV.

4. How can I get a technical proposal or quotation?
Please provide the following for an accurate specification:

System Voltage (AC or DC).

Required Mechanical Load (RML).

Pollution Level / Required Specific Creepage Distance (mm/kV).

Quantity and Project Timeline.

End Fitting Type (ball, clevis, etc.).

5. What is the insulator's construction?
It is a precision-engineered composite structure:

Core: High-strength E-CR (Electrical Corrosion Resistant) fiberglass rod, resin-impregnated, sealed with end fittings.

Interface: Critical adhesive bonding between rod, rubber, and metal end fittings.

Housing & Sheds: High-Temperature Vulcanized (HTV) Silicone Rubber or Liquid Silicone Rubber (LSR). Shed profiles (alternating diameter) are designed for specific pollution levels.

End Fittings: Hot-dip galvanized forged steel or ductile iron (Malleable Cast Iron), attached via wedge or crimping method.

6. How do you ensure long-term reliability and anti-aging?
We address the key challenges through material science and process control:

Material Selection: Premium HTV Silicone Rubber with ATH (Alumina Trihydrate) filler for arc resistance and UV stabilizers.

Core Rod Protection: Complete sealing of the rod from moisture ingress (the #1 failure mode) using advanced molding and sealing techniques.

Interface Bonding: Advanced adhesive systems and processes ensure a permanent, water-tight bond between rubber, rod, and metal.

Accelerated Aging Tests: Products undergo rigorous 1,000/5,000-hour salt fog, water diffusion, and temperature cycle tests per IEC 62217.

7. What are the different shed profiles and their purposes?
We offer profiles optimized for different environments:

Standard Profile: For light to medium pollution.

Alternating/Aerodynamic Profile: For high wind and very heavy ice loads.

Deeply Corrugated/Booster Shed Profile: For Heavy Pollution (Class III/IV) and coastal areas, maximizing creepage distance.
We can recommend the optimal profile based on your site pollution severity (SPS) class.

8. What is the "Creepage Distance" and how is it determined?
Creepage Distance is the shortest path along the insulator surface between the two metal end fittings. It is a critical design parameter determined by:

System Voltage

Site Pollution Severity (SPS) Class (per IEC 60815)
We design insulators with specific creepage distance per kV (e.g., 25mm/kV, 31mm/kV, 40mm/kV) to ensure performance in your local environment.

9. How are insulators packaged for sea freight?
We use robust, export-specific packaging:

Individual Protection: Each insulator wrapped in plastic film.

Wooden Crates or Reinforced Cartons: With internal bracing to prevent movement.

Marking: Clear labels with part number, RML, and serial number.
Packaging is designed to withstand harsh transit conditions.
