Product note
Kabeldon premolded cable connectors for 12–36 kV
CSE-A 630 A
2
Premolded connector for XLPE-insulated
1- or 3-core cables with aluminium or
copper conductors for 12–36 kV. The
connector can be used for both indoor
and outdoor applications. Type tested
according to CENELEC HD 629.1 S2 A.

1. Insulating plug
− Made of epoxy with test point.
− The outer brass plate is insulated for capacitive testing,
used for measuring locally whether the circuit is energized.
− The measurement is to be made with a suitable high
capacitive testing device.
− The test point is covered by a cap of conductive rubber
which ensures a touch-proof system.
2. Bolt
Made in brass. Thread size M16. It must be installed with a
torque wrench to achieve a reliable contact force between
the cable lug and the bushing.
3. Cable lug
− Bolted type, tested and approved in accordance with
IEC 61238-1.
− The cable lug is made of aluminium alloy and is tinplated. Can be installed on aluminium as well as copper
conductors, as the connection is encapsulated inside the
connector and is not subjected to humid conditions.
− The cable lugs are of shear-off type and designed so that
the bolts always break at the edge of the cable lug.
4. Inner conductive layer
Creates a Faraday cage around the connector that ensures
a stable electrical potential and eliminates the need for filling
material in cavities and between the conductor and cable lug.
5. Insulating layer
− High electrical strength.
− The elasticity of the material ensures active pressure on
all interfaces.
− Premoulded together with the inner and outer conductive
layer.
− Electrical properties are ensured by routine test.

Outer conductive layer
UV-, Ozone- and tracking-resistant.
UV-resistance tested for 3000 h in a xenon radiator.
Thickness 3 mm on its thinnest part.
When connected to the cable screen, the cable connector
meets international requirements for a fully screened
system.
7. Adapter
Made of field grading rubber to ensure stress control.
8. Earth connection
The conductive layer is connected to the system earth by a
copper wire. The wire can temporarily be removed from the
earth, which makes it possible to perform cable sheath tests
without disconnecting the connector from the bushing.
9. Designed for polymeric insulated cables
CSE-A can be installed on XLPE as well as EPR (flexible
rubber) insulated cables.
