Polymer Insulator Detail Information

General introduction 

HDIS-suspension composite insulator series

HDID-composite insulator ANSI class DS series

HDPIN-post composite insulator series

HDILP-line post composite insulator series

Design Feature

The composite insulator series consist of fiberglass epoxy resin lead-out rod, silicon rubber housing and hardware. Through once-molding technology and special, the silicon 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 interchanged with porcelain insulator.

Performance

1)        Excellent electrical characteristics, 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.

2)        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.

3)        Small volume, light weight (only 1/6-1/19 of the porcelain with the same voltage level),flexible structure, convenient to transportation and installation.

4)        The silicon rubber housing has great hydrophobic property, which can protect against inside wet, not require the monitor of preventive and clean, reduce daily maintenance.

5)        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°C to +50°C.

6)        Good shock resistance and collision resistance to prevent crash, bend and wrest. It can be interchanged with porcelain and glass insulator.

 Technical Specification:

1)        We propose to use corona ring at 110KV.

2)        Corona ring is necessary at 220KV and above.

3)        Different end fitting types are available on request.

4)        For application beyond the range listed here, please contact us for detail.
