SICONEX is used as a cable terminal

connector at voltages greater than 22kV in

electric equipment such as switchgears and

transformers at a substation.

When compared with existing electric

equipment belonging to the same class, it is

obvious that SICONEX has compact size and

light weight.

Outline of The Company

SWCC SHOWA CABLE SYSTEMS CO., LTD. derived from SWCC HOLDINGS CO., LTD. (formerly SWCC SHOWA

ELECTRIC WIRE & CABLE CO., LTD., found in 1936), and was established in Apr. 2006. As an integrated manufacturer

of electric power cables, telecommunication cables and cable accessories, we are contributing for infrastructures of power

transmission lines and networks not only in Japan, but also in other countries all over the world.In order to meet customers' requirements and market demands, we persist with technology innovation. Especially, for our

sophisticated power cable accessories above 22kV class, most of Japanese switchgear and transformer manufacturers

have recognized our products, and they are using it as a standard part for their switchgear and transformer.

Recently, we have developed a prestigious product: Smart Plug-in IEC type cable termination for 60kV to 345kV XLPE

insulated power cable. Our unique in-house design concept has been applied for the development of this product.

Our concept is very unique and the productsdesigned by our delicate analysis have

well-balanced electric field strength.

The reliable products produced by us conform to

International Standard due to our strict criteria of

manufacture process.

We not only provide our skilled jointing teams to you,

but also offer consultation and supervision ofcable termination work, as well as providing the

training services.

Advanced Technology

Our quality assurance system is strictly applied

in accordance with ISO 9001 Quality Management

and ISO 14001 Environment Management System.



Outdoor cable terminations including porcelain type, polymer type and direct molded type termination are

our main products. Depending on different types, outdoor terminations have various features as follows:

Porcelain type / Polymer type outdoor termination

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.

Construction Data (IEC 60859, IEC62271-209)



Cable Joint

Premolded Straight Joint

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.

Prefabricated Straight Joint

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.

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.

Y Branch Joint

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.
