General |
CIAC Cold Shrink Joint offers a reliable, fast
and easy-to-install jointing system to assure
and maintain high network reliability, and can
help you reduce the time, labor and cost involved
in a variety of electrical cable applications.
A silicone rubber joint body with integrated geometrical
stress cones provides excellent electrical stress
control. CIAC Cold Shrink Joints are designed
to cover a wide range of applications and to accommodate
the variety of cable and conductor types in the
networks. The CIAC product line covers joint needs
from 0-600V to 42 kV applications, and can be
used for direct burial, as well as in manholes,
vaults, cable trays, and junction boxes. All CIAC
cold shrink products require no special tools,
flame or training to install. |

Unique Silicon Rubber Material for Joint Body |
| |
|
| |
Silicone rubber is a kind of preferred
material for cable accessories due to its excellent
mechanical and electrical properties. For more
than 30 years silicone has been used successfully
as high-quality electrical insulation for voltages
up to 400kV.
Silicone rubber features high quality electrical
insulation, superior corona and tracking resistance,
combined with high elasticity. It facilitates
multi range application, where one product version
can be used for various conductor cross sections.
Optimal flexibility ensures easy assembly of the
accessories |
| |
|
|
| |
|
Stress Control System |
| |
|
|
|
| |
Electrical stress control is fully
integrated in the silicone joint body by well
defined conductive areas. Conductive cones with
an exactly defined geometrical design over the
screen cut area provide excellent electrical stress
control. The electrical stress control of the
connector area is made with an integrated conductive
screen performing as a Faraday cage. The coverage
of voids and edges at the connection area with
void fillers is not necessary, and the radial
electrical field can be controlled easily. |

Shield continuity: Shield Copper Mesh |
| |
|
| |
In order to keep the Shield continuity of cables,
extra Shield Copper Meshes are applied around
the joint to provide shielding and protection.

| |
|
Armorcast |
| |
|
| |
For strengthening cable and splices, armorcast
forms a tough, durable covering that will harden
in approximately half an hour. Armorcast Structural
Material is a flexible fiberglass knit fabric
strip that has been saturated with a black urethane
resin syrup. The material is rolled and packed
dry in a sealed foil envelope. Armorcast Structural
Material is completely safe for use in manholes,
vaults, and other hazardous environments, because
no heat source is required. No flames, electric
heaters, or chemicals are needed. The only thing
your crews will ever have to add is water. |
