●Product Applicability
、This product applies to rated voltage 64/110kV, nominal cross section 240mm2-1600mm2 cross-linked polyethylene power cable terminal connection. GIS Plug-in terminal for power cable connections with high-voltage transformer, Abolished the oil/oil bushing or oil/gas tube, Save a lot of space, One 110kV Short (470mm) Plug-in GIS Terminal installation (extended) out the pole, the Also applies to the 757mm type 110kV GIS Device matching.
● Features
1、all insulated parts factory pre-forming,Embedded in epoxy casing internal metal shield electrode, Rubber stress cone of imported high-temperature curing liquid silicone rubber (LSR) Materials,And optimize the product structure of the stress cone shape.
2、using spring-pressed stress cone in the cone-shaped epoxy casing wall structure, Overcome the stress cone material aging due to the flexibility of relaxation, Stress cone and cable outer semi-conductive layer of the ills of poor contact, In order to ensure long- term safe operation of the terminal.
3、terminal Dry Frame, Without adding any insulation casting agent, Therefore, there is no stress because of pre-cast cone dipped in insulating agent which accelerated aging stress cone, Improve the stress cone Life: And avoid running the terminal in the disclosureand other related phenomena occur.
4、with a light weight, small size, compact structure, easy installation and maintenance and so on.
5、the product of the performance indicators in full compliance with GB/T11017, IEC 60840 standard, Conductor with the interface in full compliance with IEC 60859-1999 standard.
6、100% factory testing, quality and stability.
