Deadbreak Connecting Plug | Richards Manufacturing
In any case the safety regulations according to the applicable national standards should be respected before taking any action to touch or disconnect the equipment.
The housing of a Euromold connector is moulded in three steps: Insulation in between jacket and insert. It is safe to remove the cap of the capacitive testpoint and to accidentally touch it without protection.
The overall available energy is minimal, any potential will disappear immediately when touched by an operator. However, according to the procedures of all Power Utilities, intended manipulation of the connectors should be done with hot stick, insulated pliers or other appropriate tools. The cable adaptors are made of a compound with high permittivity factor. This provides electrical stress relief at the semicon cut-off point of the cable.
Because the cable adaptors are not conductive, they provide a screenbreak between the cable and the connector housing. So the cable screen can be tested without disconnecting the connector from the equipment. Amongst other advantages, the EPDM connectors have a higher mechanical strength and can be easily connected and disconnected from the bushing.
The silicone connectors tend to stick to the bushing and cannot be removed easily without damaging the connector. The mastic is installed on the jacket under the bent-back Cu wire screen, to provide watersealing. The Euromold connectors are deadbreak connectors. The power has to be switched off before the connector can be disconnected from the bushing.
The connector can be pulled from the equipment with an insulating stick while the cable is still under tension. After a long time, talc powder which is mixed in the rubber mixture can rise to the surface of the connectors and form a white "layer" on the connectors - this layer can be easily cleaned and will not harm the connector's normal functioning.
The outer jacket and insert of the connector are semi-conductive. The material in between these two layers is insulating EPDM. Both kits contain 3pcs of TB connector, but the 3XTB contains installation instructions for single core cable and the TTB contains installation instructions for 3-core cable.
Keep the connectors with pin-contact Interface A and Interface B in place during short-circuit situations. The material of the Euromold connectors is resistant to UV radiation, ozone, sunlight, pollution such as salt-fog, heavy industry environments such as steel and cement works etc. The Euromold connectors have unlimited shelf life when stored in good conditions no direct sunlight, no dust,…. The test rods can be installed at the back of a T-connector or elbow connector and are used for cable fault location, cable testing, phasing checks and earthing.
As close as possible to the connector without damaging the connector. Make sure the cable is straight when clamped. Best is to clamp the cable first and then install the connector on the bushing. Why is it limited to 36kV AC - 50Hz - 1'? This AC voltage is limited to 2U0 to avoid that any damage is done by the test itself in the past there were also DC tests, but these have been replaced in most cases by VLF tests at 2U0 or 3U0. The straight forward design of the test rod no stress grading components, limited interference, no screening does not allow that high voltages as required in the normal qualification programs are applied.
And as explained above this has in fact never been the objective of these test rods. The BIPA is in contact with the contact palm. This requires a higher torque value than for the BIPA which is in contact with the clamping screw.
Because of the 3mm thick semi-conductive layer, which is connected to earth, the Euromold connectors are safe for accidental touching. This can be for a short or long time. According to the procedures of all Power Utilities, intended manipulation of the connectors should be done with hot stick and other appropriate tools.
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. Together with the watersealing mastic, the 11TL provides the water tightness of the connector at the cable entrance. It also provides a step for easy positioning of the connector. Euromold bushings are deadbreak bushings. The shaft of an in-air bushing does not need to be immersed in oil. The creepage length over the surface is long enough to install it in air and the epoxy material is resistant to UV light.
The Euromold epoxy bushings can be connected to screened separable connectors, providing a screened safe-to-touch connection. Porcelain insulators can be connected with terminations, which are open connections and thus not safe-to-touch and require larger clearance distances. Bushings are devices designed to transmit electric energy through a grounded barrier, such as the wall of a transformer or switchgear.
The Euromold epoxy bushings provide an insulated and screened connection between the conductors in the equipment and conductor of the cable.
The maximum number of cables which can be connected to a bushing, depends on the maximum allowed current, on the stability of the arrangement and on the type of interface.
Interface A and B have a plug-in interface so maximum one cable can be connected in a normal arrangement because a bail restraint is needed to hold connector in place, multiple cable arrangement for these interfaces are only possible with T- or X-connectors.
The maximum torque for the fixing studs is not officially specified, but we recommend maximum 16Nm for M10 and maximum 25Nm for M12 studs. In normal conditions SA has a high resistance R, when overvoltage occurs lightning, switching, … resistance R of the SA will drop until it is smaller than the resistance of the network and failure current will be led through the SA out of the network. Should the surge arrester be installed in front or at the back of the Euromold connector?
This makes no difference electrically. The most common installation is with the surge arrester installed at the back of the Euromold connector. Important is that the cable is properly clamped so bushing has only to carry the weight of the connector and the surge arrester.
To protect the transformers, switchgear, cables and accessories from HV surges due to lightning or switching. The creepage distance over the surface of the terminations is longer for outdoor terminations than for indoor terminations. This can be achieved by a greater length and by the use of sheds.
Restore the insulation and provide stress controll at the semicon cut-off point of the cable which is connected to equipment with a cable lug. A termination is an unscreened, not touchable connection. Minimum clearance distances have to be respected.
The shelf life of the Nexans coldshrink products is 2 years. After two years the elasticity has not changed, only the speed of retraction is less.
The Nexans heatshrink products have unlimited shelf life if stored in good conditions no direct sunlight, no dust,…. The ITK is a coldshrink termination with mastic providing the stress control.
The AIN is a slip-on or push-on termination, with a stress cone providing the stress control. What is the required environmental temperature during the installation of coldshrink products? In colder circumstances the product can still be installed, but it will take more to reach the final diameter. The function of a joint is to connect two cables to each other.
