• Model:U40B
• U   Refers To Disc Suspension Insulator
• 40 indicates a rated Mechanical failing load  of 40kN
• B   For Ball And Socket Type

• 110- indicates that the height of the insulator structure is 110mm.
• 175- indicates that the diameter of the insulator disc is 175mm.
• 190- indicates that the creepage distance of the insulator is 190mm.

• Type: Standard profile Toughened Suspension Type
•  Rated mechanical load: 40kn (about 4 tons)
• Purpose: Widely applicable as insulation support for medium and high voltage transmission lines and substation equipment, capable of stable operation under various climatic conditions.

• 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, R pin is used for U40B

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.
