Product Details
● Model: U160BL
• U Refers To Disc Suspension Insulator
• B For Ball And Socket Type
• L Stands For Long Steel Foot
● Type: Standard Profile Toughened Suspension Type
● Rated mechanical load: 160 kn (about 16 tons)
● Purpose: Usually used for transmission lines with voltage levels of 110kV, 220kV, 500kV, and higher. As a suspension insulator, it forms an insulator string and suspends wires or ground wires. Used to withstand the tension of wires in high stress locations such as corner towers and terminal towers.
● The product model is in accordance with GB/T 7253-2005 and JB/T9683-2012(EC60305:1995MOD)
● 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 U160BL.
