U40 U70BL U70BLP U120B U210BP Suspended Glass Insulator from NOOA ELECTRIC

Date:2024-09-04Tags:U40 Glass Insulator,U70B Suspended Glass Insulator,Custom Glass Insulator

Suspended glass insulator is a type of electrical insulator typically used in high-voltage power lines. These insulators are made from toughened or tempered glass, designed to support and electrically isolate the conductors from the physical structure they are attached to, such as a transmission tower. The "suspended" aspect refers to the way they are hung in series to form a string, allowing for greater flexibility and insulation strength.

Main Electric Insulators : Standard-Type Glass Insulator (U70/U120/U160/U210/U300) , Antipollution-Type Glass Insulators (U120bp/U160bsp/U210bp), Aerodynamic Type Glass Electrical Insulators (Ug70bsa/U100bsa/U120bla), Multi-Umbrella Type Electric Insulators, Ground-Wires Type Glass Power Line Insulators (U70cn/U100cn/U120c), Post Insulator For Line, Pin Glass Insulator. Products Are Mainly Used For Transmission Line Insulation, Suspension, Support, Tension Conductors. They Are Divided Into 5 Major Series: The Standard Type Glass Insulator 40-550kn, Filth-Resistant Type Glass Insulators 70-420kn, Aerodynamic Type Glass Electrical Insulators 120-300kn, Multi-Umbrella Type Electric Insulators 120-300kn, And Ground Circuit Type High Voltage Insulators, Able To Be Used For Line Voltage From 10kv～1000kv.
