High Voltage Composite Polymer Insulator is an advanced type of insulator used in electrical power systems to support and isolate high-voltage conductors. These insulators are designed to withstand high electrical stress, mechanical loads, and environmental conditions. They are increasingly replacing traditional ceramic or glass insulators due to their superior performance and durability.
These composite polymer insulators must comply with international standards such as IEC 61109, IEC 61952, and IEEE 1523.
They undergo rigorous testing for electrical, mechanical, and environmental performance.
The construction of a High Voltage Composite Polymer Insulator is a critical aspect of its design, ensuring it meets the required electrical, mechanical, and environmental performance standards. Below is a detailed explanation of the construction of these insulators, broken down into their key components:
1. Core (Load-Bearing Component): Made of fiberglass reinforced epoxy resin. Provides the insulator with high mechanical strength to withstand tensile, compressive, and bending loads.
2. Weathersheds (Outer Housing): Made of silicone rubber or ethylene propylene diene monomer (EPDM). Protects the core from environmental factors and provides electrical insulation.
3. End Fittings (Metal Attachments): Made of galvanized steel, aluminum, or ductile iron. Connects the insulator to the transmission line or support structure.
| Type | Rated voltage(kV) | Specified mechanical load(kN) | Section length(mm) | Min Arc distance(mm) | Leakage distance(mm) | Lightning impulse withstand BIL(kV) | Power frequency withstand (wet) (kV) |
| FPQ-12/4 | 12 | 4 | 215 | 125 | 280 | 75 | 42 |
| FPQ-15/5 | 15 | 5 | 250 | 180 | 370 | 105 | 42 |
| FPQ-24/8 | 24 | 8 | 305 | 255 | 715 | 150 | 75 |
| FPQ-36/8 | 36 | 12 | 440 | 360 | 1100 | 185 | 95 |
| FPQ-36/8 | 36 | 12 | 440 | 360 | 1300 | 185 | 95 |
Transmission Lines: Used in overhead power lines for high-voltage transmission (typically 11 kV and above).
Substations: Employed in substations for busbar support and equipment insulation.
Railway Electrification: Used in overhead catenary systems for railways.
HVDC Systems: Suitable for high-voltage direct current (HVDC) applications.
Use wooden boxes and plastic packaging to protect the products from physical damage, moisture, and environmental pollutants.
Delivered worldwide via sea, air, or land freight. Custom shipping solutions are available based on customer requirements.
