Product Details

70kN 220kv Open Air Aerodynamic Disc Glass Insulator for High Voltag

Model:U70BSA/U70BLA
U Refers To Disc Suspension Insulator
70 indicates a rated Mechanical failing load of 70kN
B For Ball And Socket Type
S Stands For Short Steel Foot
L Stands For Long Steel Foot
A Aerodynamic design

127/146- indicates that the height of the insulator structure is 127mm, and there are also insulators with spacing of 146mm.
380- indicates that the diameter of the insulator disc is 380mm.
365- indicates that the creepage distance of the insulator is 365mm.

Type: Open profile Toughened Suspension Type
Rated mechanical load: 70kn (about 7 tons)
Purpose: Aerodynamic glass insulators are primarily used in high-voltage transmission lines. Their Aerodynamic design resists strong winds, reduces vibration, prevents ice buildup, and enhances self-cleaning capabilities. They are ideal for harsh weather conditions (e.g., windy or frigid regions), ensuring line stability and safety.

The product model is in accordance with IEC60383-1:1993，MOD / GB/T1001.1
The connection structure is in accordance with GB/T4056-2008(IEC60120:1984,MOD) and BS 3288 part lll.
According to customer requirements, the locking pin can be either W-pin or R-pin.
lf there is no special instruction, W pin is used for U70BA
