Glass insulator CTV255 U70BS
Glass insulator CTV255 U70BS
Diameter: 255mm
Height: 127mm
creepage distance: 320mm
we ourself produce glass piece with our aobest marking, have three reasons:
1:to avoid no resource for glass piece ,
2: Break the monopoly of the market in short and no goods for glass parts
3: provide competitive price and good quality for clients.
