ANSI 52-3 suspension insulator widely use on high voltage transmission line, it also connected with a telephone pole. 52-3 insulator product according to ANSI standard, the connected type of it is socket & ball
Epoxy resin insulator of 3k～70kV which is made by automatic pressure gelation is available. It can be used as the insulating supporter for mounting instruments to Distribution Panel Board, Control Board, Rectifier Board, and the wiring of Bus bars and Wires.
Orient power composite hollow insulators are also of highest quality: Manufactured in accordance with IEC, ANSI and other standards. Composite hollow insulator us installed in explosion-proof switchgear that are usually exposed to aggressive contamination and weather conditions during operation
Composite insulator for railway traction lines is used in tunnels of electrified railway under severe conditions. They can effectively prevent pollution flashover outage and free from cleaning and maintenance work. It will hold on not only tension, but also bending. With a very small size, they can hardly be substituted by porcelain or glass insulators in case if small tunnel space.
Polymer cross arm insulator has an effective use of a narrow corridor pressure transmission and applicable to rebuild of city power net. It can also reduce the tower height, saving manpower, material and financial resources.IT has a seperiod performance than porcelain insulator.
Orient power started commercial production of polymer line post insulator since 1978, now we can offer line post insulators for transmission line applications of various voltage classed up to 132kv.
Polymer guy strain insulator are manufactured from high grade silicone rubber and fiberglass rod to ensure a life time of trouble free service. These insulators are protected from the environment including the effects of voltage, ultra-violet rays and acid rain by a fully bonded, electrically track-free, and impenetrable silicone rubber sheath.
Composite tension insulator can be used in overhead transmission line or distribution line, and the voltage can be from 10kv to 1000kv.Composite tension insulator is main used in tension tower to assemble tension string to tensile conductor.
Composite dead end insulators is used for dead end structures which are used the transmission line either ends to follow a substation or when it turns through a large angle. Composite dead end insulators are designed according to IEC61109 and ANSI C29.13.
Composite pin insulators are made of an insulating fiber glass core, HTV silicone rubber and supporting and mounting fittings, the voltage ranges from 6kv to 36kv.
Silicone rubber type post insulator is one of high voltage insulator which used for substation, switchgear and electrical apparatus. And silicone rubber type post insulator main have four mechanical loading when design, that is: compression, cantilever, tensile and torsion.
