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 ,the silicone rubber housing and core rod were 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,the insulator has the advantages of high mechanical strength,nice figure,small volume,less weight.Another advantage is the hardware which plated zinc to resist erosion,can be intercharged with porcelain insulator.
3.Performance
a.Excellent electrical characteristic,high mechanical strength,and the extension intensity of fiberglass epoxy resin lead-out rod has 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 require clean.The flashover voltage is 1.6-2 times than the same creepage of porcelain insulator.It is very useful in heavy pollution 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 preventive 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.
