HDPE insulators can be divided into HDPE pin insulators and cable spacers. HDPE insulators can not only provide better electrical performance but also mechnical strength. Plus it is recycable, recent years it is popular to change original porcelain or polymer types.
HDPE insulators are injected with high density polyethylene, and need high technique and better injection machine to keep no voids in the insulator head. Orient Tec provide laser inspection for the inner structure for each insulators to keep the insulator has better mechnical strength and puncture value.
HDPE pin insulator are used on 15-35 kv distribution insulators lines, and assemble with steel head spindle. We also provide nylon head spindle together with the HDPE insulators in order to protect the thread and provide better insulation.
Orient Tec produces more than 100000pcs HDPE insulators per year and the market is growing. There is no special standard for HDPE insulators now, normally it refers to IEC62217 and IEC60383.
Overhead Line Fittings
Insulator and conductor fittings for overhead power lines have many types. BS3288 gives the performance and test requirements of them. The overhead line fittings connect the conductor to the insulators and towers or apparatus, or protect and repair the conductors and so on.Learn More >
In distribution lines, composite tie top line post insulators are the same as composite pin type insulators. The base fitting is the cap which assemble with the crossarm by steel studs. The head fitting can be steel type, or HDPE type, nylon type or silicone rubber covered types.Learn More >
