The 69kV rod-type suspension composite insulator is a high-performance insulation product widely used in high-voltage power transmission lines and substations. It offers excellent electrical insulation and mechanical strength. Designed with advanced composite materials and a rod-style suspension structure, this insulator is ideal for long-term outdoor applications in harsh environments.
This composite insulator consists of three main parts:
Fiberglass-reinforced epoxy resin core rod: Delivers high tensile and bending strength.
Silicone rubber housing: Features superior hydrophobicity, aging resistance, and pollution resistance.
Metal end fittings (hot-dip galvanized steel or aluminum alloy): Ensure firm mechanical and electrical connections.
The entire insulator is produced using a unified injection molding process, guaranteeing tight sealing and defect-free construction.
Rated Voltage: 69kV
Power Frequency Withstand Voltage (Dry/Wet): ≥140kV
Lightning Impulse Withstand Voltage: ≥250kV
Tensile Strength: ≥70kN
Creepage Distance: ≥1725mm
Installation Type: Suspension
Operating Temperature: -40ºC to +85ºC
Insulation Material: Epoxy fiberglass core + silicone rubber housing
High Electrical Insulation: Excellent dielectric strength and pollution flashover resistance.
Lightweight and Easy Installation: Significantly lighter than porcelain insulators, reducing labor and logistics costs.
Weather Resistant: Corrosion-resistant and UV-resistant, suitable for coastal and industrial areas.
Superior Mechanical Strength: Meets the needs of high-tension transmission lines.
Long Service Life: Self-healing hydrophobic surface reduces pollution buildup.
The 69kV rod-type suspension composite insulator is widely used in:
Urban and rural high-voltage power distribution lines
Transmission towers and substation structures
High humidity, high salt, or heavily polluted areas
Wind and solar energy power transmission systems
This insulator is suitable for 66-72.5kV transmission projects and is an ideal replacement for traditional porcelain insulators.
