A cable gland having a first cable gland portion and a second cable gland portion in engagement with each other is disclosed. The cable gland comprises earthing members (60) in electrical engagement with the first and second gland portions, each earthing member including a spike (68) for penetrating through a sheath layer of an electrical cable, following radially inward movement of the spike, thereby forming an electrical earth connection with a conducting portion of a cable. The first gland portion comprises a first cam surface and the second gland portion comprises a second cam surface, wherein the first and second cam surfaces are adapted to engage respective earthing member cam surfaces (72, 74) of the earthing member, the first and second cam surfaces thereby causing the earthing member and the corresponding spike to move radially inwards as the first and second gland portions are brought into threaded engagement with each other.

A terminal fitting includes a cylindrical portion having a first crimping region and a second crimping region. A crimped state of a braided body extending through the terminal fitting is formed between the terminal fitting and a cable at the first crimping region such that relative movements of the terminal fitting and the braided body are prevented, and an end of the braided body is then folded back and positioned to face an outer surface of the cylindrical portion in a radial direction. The crimped state of the braided body is then formed between a sleeve and the terminal fitting at the second crimping region, so that the terminal fitting is fixed to the braided body.

A high-voltage device for receiving a high-voltage cable having a conductor designed to conduct an electrical current and a cable insulation surrounding the conductor, includes an insulation and a waveguide. The insulation includes an at least partly transparent or translucent field control unit from a siloxane polymer which is designed to at least partly surround the cable insulation of the high-voltage cable, the siloxane polymer including, in at least one portion of the field control unit, covalently bonded fluorophores and/or dielectric pigments. The waveguide is arranged such that a light signal caused by a partial discharge in the field control unit can be coupled from the field control unit into the waveguide.

A power cable with a termination connection box. The power cable includes a conductor, an inner semiconducting layer, an insulating layer, and an outer semiconducting layer which are sequentially formed. The termination connection box includes: a porcelain tube configured to provide an inner space into which an end portion of the power cable from which portions of the outer semiconducting layer, the insulating layer, and the inner semiconducting layer are sequentially removed is inserted; and a reinforcing insulating layer configured to cover an outer side of the insulating layer of the power cable so as to reinforce dielectric strength of a portion of the power cable from which the portion of the outer semiconducting layer is removed and at which an electric field is thus concentrated.

A cold shrinkable termination has an electric power cable, an insulation body, and a stress control tube. The electric power cable has a conductor core, an insulation layer covering the conductor core, and a conductive shielding layer covering the insulation layer. The insulation body has a first end portion and an opposite second end portion. The stress control tube is disposed in the insulation body adjacent to the second end portion of the insulation body. The stress control tube has a first tube portion directly overlapped on the insulation layer of the electric power cable, and a second tube portion directly overlapped on the conductive shielding layer of the electric power cable and extending a predetermined length thereon when the cold shrinkable termination is mounted on the electric power cable.

An inventive method of mounting a cold shrinkable termination on an electric power cable has the steps of: providing a support tube having an outer surface coated with a soft material comprising a gel or a sealing compound on a predetermined segment; pre-expanding an insulation body of a cold shrinkable termination on the support tube coated with the soft material; inserting a cable joint of the electric power cable having a portion of a conductive shielding layer and a portion of an inner insulation layer removed, into the support tube; and removing the support tube from the cold shrinkable termination such that the cold shrinkable termination shrinks on the cable joint of the electric power cable, and the soft material is positioned between the cold shrinkable termination and the cable joint.
