The present disclosure provides a curable casting resin precursor, comprising (a) a first part (A) comprising: (a1) at least one epoxy resin; (b) a second part (B) comprising: (b1) at least one first amine-based epoxy curing agent; (b2) optionally, at least one second amine-based epoxy curing agent; (b3) at least one mineral filler; (b4) at least one phenolic lipid; wherein part (A) and/or part (B) comprise at least one triphenylmethane dye. The curable casting resin precursor is suited for encapsulating metal parts such as cable joints and the like.

Epoxy casting resin formulation

An assembly for covering at least a portion of a cable, such as an electric cable, comprises an elastomeric tube and a hybrid support core structure. The hybrid core structure includes a central core structure formed from a spirally wound separable ribbon that supports a central portion of the elastomeric tube in a radially expanded state, and first and second solid end core structures that support first and second end portions of the elastomeric tube in a radially expanded state. Each solid end core structure has a film disposed on at least an inner surface thereof having a coefficient of friction less than or equal to 0.05.

Cover assembly with hybrid core structure

Voltage sensor () for a high- or medium-voltage power-carrying conductor for a power network, such as an inner conductor of a power cable or a cable connector or a bus bar. The voltage sensor has a tubular shape and an axial passageway (), which can receive the conductor. The voltage sensing device comprises a) a radially-inner electrode (), operable as a first sensing electrode of a sensing capacitor for sensing the voltage of the power-carrying conductor, b) a radially-outer electrode (), operable as a second sensing electrode of the sensing capacitor, and c) a solid carrier element (), at least a first portion of which is arranged between the inner electrode and the outer electrode, the first portion being operable as a dielectric of the sensing capacitor. The sensor can be accommodated in a cable accessory. The carrier element may comprise ceramic material to increase accuracy.

Voltage Sensor

Cable connection device for connecting a power cable to an electrical installation of a power network, comprising a conductor element having a first end portion, a second end portion, and a middle portion disposed between the first and the second end portion. The conductor element comprises a connector socket arranged at the first end portion, for mating with a cable plug. The connector socket is integrally formed with the middle portion.

Cable connection device

The tubular terminal for a cable, in particular a medium or high voltage cable, comprises a first connector having at least one terminal end for connecting to at least one mating second connector adapted to be connected to a cable and engaged with the first connector for making electrical contact therewith upon connection of the second connector to the at least one terminal end of the first connector. Furthermore, the tubular terminal comprises a shrinkable sleeve having a first tubular portion and a second tubular portion extending from the first tubular portion. The first tubular portion of the shrinkable sleeve is fixedly arranged around the first connector. The second tubular portion of the shrinkable sleeve is adapted to extend beyond the at least one terminal end of the first connector for covering a mating second connector and cable attached thereto when the second connector is connected to the at least one terminal end of the first connector.
