IEC TS 60859:1999 pdf download – Cable connections for gas-insulated metal-enclosedswitchgear for rated voltages of 72,5 kV and above -Fluid-filled and extruded insulation cables – Fluid-filled and dry type cable-terminations.
This technical specification covers the connection assembly of cables to gas-insulated metal- enclosed swltchgear in single- or three-phase arrangements where the cable-terminations are fluid.fllled and there Is a separating insulating barrier between the cable insulation and the gas insulation of the switchgear. It is also applicable to connections with extruded insulation cables provided that these are fitted with cable-terminations which are fluid-filled.
This specification also covers the connection assembly of extruded insulation cables to gas- insulated metal-enclosed switchgear in single- or three-phase arrangements where the cable- terminations are of the dry type. The cable-termination design comprises an elastomeric electrical stress control component in intimate contact with a separating insulating barrier between the cable Insulation and the gas Insulation of the switchgoar. The cable•termlnatlon does not include any insulating fluid.
The purpose of this report is to establish electrical and mechanical interchangeability between cable-terminations and the gas-insulated metal-enclosed switclgear and to determine the limits of supply. It complements and amends. if necessary. the relevant IEC standards.
For the purpose of this specification the term switchgear is used for gas-lnsulated metal- enclosed switchgear.
It does not cover directly immersed cable-terminations, as described in CIGRE brochure 89.

3Definitions
For the purposes of this technical specification,the following definitions apply.
3.1
cable-termination
equipment fitted to the end of a cable to ensure electrical connection with other parts of thesystem and to maintain the insulation up to the point of connection.Two types are describedin this specification
3.1.1
fluid-filled cable-termination
cable-termination which comprises a separating insulating barrier between the cableinsulation and the gas insulation of switchgear.The cable-termination includes an insulatingfluid as part of the cable connection assembly
3.1.2
dry type cable-termination
cable-termination which comprises an elastomeric electrical stress control component inintimate contact with a separating insulating barrier between the cable insulation and the gasinsulation of the switchgear. The cable-termination does not require any insulating fluid
3.2
main-circuit end terminal
part of the main circuit of the gas-insulated metal enclosed switchgear forming part of theconnection interface
3.3
cable connection enclosure
part of the gas-insulated metal-enclosed switchgear which houses the cable-termination andthe main-circuit end terminal
3.4
cable connection assembly
combination of a cable-termination， a cable connection enclosure and a main-circuit endterminal which mechanically and electrically connects the cable to the gas-insulated metal-enclosed switchgear
3.5
design pressure
pressure used to determine the thickness of the enclosure and the components of the cable-termination subjected to that pressure (according to lEC 60517, clause 3).
