In modern power transmission systems, the 36kV long rod composite insulator serves as a crucial insulating component. It is widely used in substations, overhead transmission lines, and other high-voltage environments. Compared to traditional porcelain insulators, composite insulators offer superior electrical and mechanical performance as well as strong anti-pollution capabilities.
The 36kV composite insulator consists of three main components:
Core Rod: Made of high-strength epoxy fiberglass (FRP), offering excellent tensile strength.
Insulating Sheath: High-grade liquid silicone rubber with outstanding weather, UV, and pollution resistance.
End Fittings: Hot-dip galvanized steel with anti-corrosion treatment, adaptable to various mounting conditions.
| Item | Specification |
|---|---|
| Rated Voltage | 36kV |
| Power Frequency Withstand | ≥85kV (dry), ≥65kV (wet) |
| Lightning Impulse Withstand | ≥170kV |
| Tensile Strength | ≥70kN |
| Creepage Distance | ≥900mm |
| Insulation Distance | ≥450mm |
| Operating Temperature Range | -40ºC to +90ºC |
| Tracking Resistance Level | ≥Grade 4 (IEC60587 Compliant) |

Superior Electrical Insulation: High voltage tolerance and excellent anti-tracking performance.
High Mechanical Strength: Fiberglass rod ensures strong tensile and bending capacity.
Pollution Flashover Resistance: Silicone surface has self-cleaning properties, ideal for heavy pollution zones.
Lightweight & Easy to Install: 30%-40% lighter than porcelain types, reducing installation workload.
Long Service Life: Excellent aging resistance, with over 20 years of outdoor usage expected.
This insulator is suitable for transmission lines, substations, electrified railways, wind and solar power systems operating at 36kV or lower. It is especially recommended for coastal areas, deserts, heavily polluted industrial zones, and high-altitude regions.
We provide flexible customization services including length, voltage class, end fitting types, and pollution class. OEM/ODM partnerships are welcome. All insulators are 100% high-voltage tested before delivery to ensure reliable quality.
