1. General introduction
HDIS-Suspension composite insulator series
HDID-Composite insulator ANSI class DS series
HDPIN-Pin type composite insulator series
HDIP-Post composite insulator series
HDILP-Line post composite insulator series
2.Design features
The composite insulator series consist of fiberglass epoxy resin lead-out rod,silicone rubber
housing and hardware.Through once-molding technology and special making,the silicone
rubber housing and core rod are tightly integrated,so accidents caused by the interface
electrical breakdown are avoided.With special colloid installation and compression joint
technique in the connection of the fiberglass epoxy resin lead-out rod and the hardware
fittings,the insulator has the advantages of high mechanical strength,nice figure,small
volume,less weight.Another advantage is that the hardware,which plated with zinc to resist
erosion,can be interchanged with porcelain insulator.
3.Performance
a.Excellent electrical characteristic,high mechanical strength,and the extension intensity of
fiberglass epoxy resin lead-out rod have 2 times stronger than general steel,10 times higher
than porcelain material.It could be more safe and reliable.
b.Good resistance to soiling and flashover,not required to be cleaned by hand.The flashover
voltage is 1.6-2 times higher than the same creepage of porcelain insulator.It is very useful in
heavy polluted area.
c.Small volumn,light weight,(only 1/6-1/19 of the porcelain with the same voltage level )
flexible structure,convenient to transportation and installation.
d.The silicone rubber housing has great hydrophobic property,which can protect against inside
wet,not require the monitor of preventation and clean,reduce daily maintenance.
e.good sealing performance,strength anti-electrical erosion,the tolerance leakage degree
reaches TMA 4.5 degree the product,have excellent resistance to erosion,resistance to low
temperature and can be applicable for the ambient temperature from -40 degrees to
+50degrees.
f.good shock resistance and collision resistance to prevent crash,bend and wrest.It can be
interchanged with porcelain and glass insulator.
