Composite line surge arresters offer unique features which contribute to improve the quality of service of your High Voltage system by eliminating flashovers due to lightning, as well as solution to specific needs.

Composite line surge arresters are also a safety device that will protect the crew, the equipment and people in the vicinity. For enhanced performance of your High Voltage system, you can rely on Orient's expertise with:
More than 300.000 Orient surge arresters in service worldwide from 45 kV up to 400 kV
30 years’ experience in composite technology using direct injection molding of the polymer housing under high pressure and high temperature
Customized study for a reduced number of line arresters.
The determination of the line surge arrester design, as well as their optimal location, is done by our experts, using state of the art transient simulation software that take into account the parameters of your line.

Advantages of the Composite line surge arresters / polymer housed surge arresters:
Increased life time of the ZnO blocks which are protected from moisture ingress thanks to our impenetrable design
Excellent mechanical characteristics due to the reinforced fiber glass tube
Excellent pollution performance of the silicone housing
Excellent protection performance due to very stringent selection of extra high quality, high energy duty metal oxide blocks
Increased safety of surrounding crew and equipment thanks to the explosion proof design (air-free)
Easy to install and transport due to the low weight
Reduced space requirements thanks to a compact design

Composite line surge arresters Specific needs and solution:
Protection of Zno blocks: No risk of moisture ingress thanks to impenetrable housing and air free design
Safe behaviour in the event of a fault: Explosion proof thanks to a specific composite design
High mechanical strength: FRP tube providing high mechanical strength and protection of the blocks
Protection of key points of the system: Expertise able to determine optimal arrester location using transient simulation software

Orient Power offers a range of composite surge arresters in conformity with IEC 60099-4. > Class: 1, 2 and 3
