This termination consists of a stress relief cone, insulating materials, and metals such as a protective cover and a connecting rod. It has a simple structure with stable performance. The stress relief cone is manufactured in a clean room by using high-quality silicon rubber. The insulating bushing can be provided with porcelain type one or polymer type one in accordance with the customer's requirements.

The SF₆ gas/oil immersed sealing end is a dry type cable termination which is completely free from liquid insulation and fully complies with international standard. The products are ranging from 60kV to 345kV. The product consists of an epoxy insulator, an electrical stress relief cone, compress unit, and other parts. The epoxy insulator is made from the epoxy resin of highest grade of quality and manufactured in the complete close production line under the contamination-free condition in our factory.

• ^*1:The dimensions of the SF6 gas/oil immersed sealing end are provided in the IEC 60859, IEC 62271-209. For detailed dimensions, refer to the table 1 or 2.
• ^*2: The dimensions of the oil immersed sealing end are determined by deliberations with a customer.

The premolded straight joint consists of a rubber block unit, insulation compound, a connector, and protective covers. The rubber block unit is premolded by using high-quality silicon rubber in the factory. It is pre-expanded with a spiral core in the factory and can be installed only by pulling the spiral core at the site. Therefore the special tools and high skill are unnecessary at the assembly process, so those shorten the assembly time and stabilize the product's performance.
According to the customer's requirements, a coffin box can be used optionally. The joint without coffin box can also meet waterproof requirements due to its protective copper tube with plastic waterproof coating.

The prefabricated joint consists of an epoxy unit, a connector, two stress relief cones, and two protective covers. The surface pressure between the cable, the stress relief cone, and the epoxy unit is maintained and guaranteed by a mechanical force of the compression device's springs. So the stabile performance is demonstrated by more past records.

The Y branch joint consists of an epoxy unit, three stress relief cones, and three compress units. The epoxy unit is made from highest grade epoxy resin and manufactured under the contamination-free condition. It has a small dimension compared with the conventional type and can cover XLPE cables with conductor size up to 1200mm². The Y branch joint is a dry-type structure without oil/gas-filling so that there is no need to maintain regularly and there is no factor of fire trouble.
