Description
Connecting and ekrano-dividing EHVS couplings on tension from 123 kV to 170 kV Application of "Trekhkomponentnaya" the design of the coupling is intended for cables with plastic isolation with various types of screens and metal covers on tension from 123 kV to 170 kV. Feature of a design • The "Trekhkomponentny" design • Bolted mechanical connectors • Sealing by thermofusible glue on TU tubes • Small length of cutting of a cable • Is not required special tools for installation • A possibility of division of screens • A possibility of connection of cables with different sections • Silicone elements of the case pass obligatory production tests • Tests according to MEK 60840 and IEEE 404
Basic elements of a design Miftah consists of a connector (1), cable tension adapters with cones of VNEP (2) and the tension case of the coupling (3) covering adapters (2) and a zone of a connector (with Faraday's cell) (7). External protection and sealing is carried out by TU tubes and cuffs (9, 12). Veins of a cable connect to the help of a bolted mechanical connector (1). This connector is intended for multiwire aluminum and copper veins. It can be also established also on seamless veins. Internal diameters of cable adapters from silicone rubber (2) are made under concrete diameters on isolation and the screen of cables. External diameters remain invariable. Thus, diameters of area of connection are leveled. It allows to block several various sections of a cable one insulating case of the coupling (3). Thus, joining of cables with various sections is possible without any additional accessories. Thanks to plasticity of cable adapters (2) and the main case of the coupling (3) there is no need for special tools for their installation on a cable. The metal filter (7) over a connector provides fine transfer of heat and a smooth transitional surface. The fixing rings (6) provide a necessary arrangement of the cable adapter in relation to phase isolation of a cable. In the course of installation of the coupling the tension case of the coupling temporarily parks on an external cover of a cable. It allows to execute shorter cutting of a cable and it is essential to reduce installation time. Connection of metal screens and covers is made in the mechanical nepayanny way (8). The tube (9) and a cuff (12) are applied by TU to shielding of a zone of connection and its sealing. The coupling design with division of screens is similar to a design of the connecting coupling. Grounding conductors with double isolation are brought out of the coupling by means of special TU of the pressurizing components.
