Product Details
- Model:U300BD
- U Refers To Disc Suspension Insulator
- 300 indicates a rated Mechanical failing load of 300kN
- B For Ball And Socket Type
- D For Double Shed profile glass Insulator
- 320- indicates that the diameter of the insulator disc is 320mm.
- 195- indicates that the height of the insulator structure is 195mm.
- 480- indicates that the creepage distance of the insulator is 480mm.
- Type: External shed profile Toughened Suspension Type
- Rated mechanical load: 300kn (about 30 tons)
- Purpose: primarily used in high-voltage transmission lines in areas with heavy pollution or humid, rainy conditions. Their double-shed design effectively enhances anti-pollution flashover performance, ensuring stable operation of the power system.
- 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 U300B.
