U100bla 70kN 220kv Open Air Aerodynamic Disc Glass Insulator for High Voltag

• Model:U100BSA/U100BLA
• U   Refers To Disc Suspension Insulator
• 100 indicates a rated Mechanical failing load  of 100kN
• 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: 100kn (about 10 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 U100BA

Suspension insulators consist of the following elements:

• - One dielectric made of toughened glass with the appropriate properties and shape for the environmental conditions in which it must function.
• - One hot-dip galvanized nodular or ductile malleable cast iron cap.
• - One hot-dip galvanized forged steel pin.
• - The cap and pin are assembled on the glass piece using aluminous cement with the appropriate properties to withstand the thermomechanical efforts.

Lastly, the insulator cap has a stainless steel or phosphor bronze locking device (split pin) which secures the coupling of the units.

Similarly, the pins may be protected using an anti-corrosion zinc sleeve (sacrificial anode), when requested. This zinc sleeve is strongly recommended for insulators which are going to be used in lines with heavy pollution.
