What’s the raw material used to make the separable connectors?
Silicone rubber and EPDM rubber.
What is the use of the test rod?
The test rods can be installed at the back of a T-connector and are used for cable fault location, cable testing, phasing
checks and earthing.
Why there is no test rod available for type A Interface connector?
The design of the test rod is such, that it needs to be in contact with the conductor of the cable. This is possible for T-
connectors, and for Elbow connectors with a removable plug. This is not possible for Interface A connectors.
What is the IP rating of the separable connector?
The IP (Ingress Protection) rating of the separable connectors is IP67. This means that the connectors are completely
dust-tight and suitable for immersion in water of <1m depth.
What is the function of the bail restraint?
Keep the connectors with pin-contact (Interface A and Interface B) in place during short-circuit situations.
What does the sealing mastic used for?
The sealing mastic is installed on the jacket under the bent-back Cu wire screen, to provide watersealing.
Are the separable connectors water tight?
Yes, the separable connectors are completely watertight, both at its interfaces and at its cable entrance. In case of Cu
wire screen, water sealing mastic is applied on the cable jacket, to prevent moisture ingress into the cable.
What is the function of a bushing?
Bushings are devices designed to transmit electric energy through a grounded barrier, such as the wall of a
transformer or switchgear. The epoxy bushings provide an insulated and screened connection between the conductors
in the equipment and conductor of the cable.
