Problems solved by technology

[0006] However, this method has several disadvantages, since the method involves several steps, the end user will not be able to easily and quickly terminate the cable
Additionally, there is a one-step operation that requires special tooling to crimp the connector to the conductors of the cable, and the end user doing the cable termination has to deal with several separate parts

Embodiment Construction

[0041] figure 1 A perspective view of a terminating head 10 of a medium-voltage cable 12 comprising a conductor 14 which can be raised to potential V is schematically shown.

[0042] In this first embodiment, the terminating tip 10 is in the form of a generally elongated body 16 .

[0043] The main part 11 of the body, along the longitudinal dimension L, presents, referenced 16a, a generally cylindrical shape with a generally constant transverse dimension d1.

[0044] The substantially cylindrical shape of the constant transverse dimension allows the terminating tip to fit preferably into a radially shrinkable sleeve, such as the one disclosed in document EP 0435569 .

[0045] Thus, the cable termination lug of the invention can be encapsulated with such a radially shrinkable cylindrical sleeve encapsulating the connection between two cables without any modification to the sleeve having an approximately constant inner diameter.

[0046] The body 16 presents, over the remaind...

Abstract

The invention relates to a terminating head for medium-voltage cables containing conductors that can be raised to potential V, characterized in that the terminating head is in the form of a body (16; 72) of generally longitudinal shape, which it is called One end being the first end (18a; 74a) is attached to the conductor of the cable so as to mechanically fix the conductor to the body, wherein the body has an opposite end, called the second end (16; 76), wherein at least the The second end portion has an insulating function.

Description

field of invention [0001] The invention relates to terminating lugs for medium voltage cables comprising conductors which can be raised to potential voltage (V). Background of the invention [0002] Power transmission at medium voltages, ie voltages or potentials (V) between about 1 KV and 50 KV is usually done by cables connected together by junctions. [0003] When the cable is installed and terminated as described above, the end of the cable can be connected to a unit which converts or steps down the voltage, for example, from 20KV to 220V. [0004] When the cable is neither connected to the voltage conversion unit nor connected to the other end of the cable via a joint, it is required to at least temporarily protect the end of the cable, which in some cases can rise to potential V. This may be necessary, for example, while waiting for the end of the cable to be connected to the other end of the cable or to a voltage conversion unit in anticipation of the extension of th...
