6 Introduction General Why ring connectors... It is daily business to connect a mains cable to a branch cable, especially in low voltage cable networks, for instance for a house service connection. In former times mains cables were stripped at the installation point and the insulation was removed. Branches were made with simple bare branch connectors. Live installation of course was impossible under such conditions, so the mains cable and all connected consumers were without electric energy until the job was done. To minimise disturbance of consumers and to increase working safety for the electrician, insulated single connectors were developed, to be installed on insulated conductors. These connectors are provided with teeth, cutting edges or screws which spare removal of insulation from conductors, and enabled live installation when used with personal protection equipment and insulated tools. Duration of installation was reduced considerably and at the same time safety of the electrician was increased. Furthermore possible cable damage was reduced (entering of moisture, breaking strands) as the insulation as conductor protection cover remained nearly undamaged. 6

7 Introduction In most cases all phases of the mains cable were to be branched, so consequently the next development step was from a single connector to a multiple one. This multiple branch connector (in short: ring connector) enables branching of a cable on all phases under voltage, in narrowest space. Today this becomes even more important under the aspect of time and cost saving. General ARCUS Ring Connectors offer several advantges: safe live operation vast cross sectional range for mains and branch cables deliberate contacting of live conductors by use of screws contact sequence definable, for instance neutral conductor first uniform key size for all contact screws equalisation of creepage and expansion processes by use of spring washers Today's multitude of ring connectors relates to manifold cable constructions in low voltage networks. Ring connectors for 3-, 3 1/2- and 4-core cables, cables to standards DIN VDE, TGL or other standards, or ring connectors for large or for small cross sections are a consequence of a multitude of cables. Beside the multitude of cables also different joint systems or working methods play a role. Ring connectors with grub screw or shear-head screw, ring connectors with axial or radial branch, and ring connectors with increased insulating properties are the result.

8 Introduction The following pages summarise the main ring connector details in tables. General Due to limited space and necessity to focus on the main features, we have used terms and abbreviations that may not be clear at first sight. On this page you will find the explanation for these terms and abbreviations ,6 1) Diameter of a circle which totally encircles the installed ring connector (seen in direction of mains cable). This dimension is important to select the suitable joint (see picture 1). 2) Dimension for expansion of ring connector in direction of mains cable. 3) R stands for a radial of branch contact screws in relation to mains cable (see picture 2). 4) T stands for a tangential of branch contact screws in relation to mains cable (see picture 3). 5) SW(i) Wrench size for hexagonal socket of contact screws, wrench sizes of assembly tools are described in DIN ) SW(a) Wrench size for hexagonal head of contact screws, wrench sizes of assembly tools are described in DIN 475.

19 Ring Connector for Cable to TGL Standard and other Uncompacted Aluminium Cables Wedge type A Cross Section [mm²] Ring Connector Contact Screw Dimensions [mm] Mains Branch Wedg es Number 4-Core Cable Mains Branch maximum outer diameter width length of diameter of screw screw with shear head socket screw radial R tangential T SW(i) (DIN 475) torque [Nm] 120 SM -240 SM 1) 150 SE SE 6-70 SM 95 SE / 6 20 A Explanation cross sections: S=sectorial, E=solid, M=stranded 1) 240 SM only after consultation with ARCUS Schiffmann This ring connector was designed especially for cables to TGL Standard. Here the mains screws are provided with two shear-off positions to meet the demands of the special TGL cable construction, an uncompacted cable conductor. After piercing the conductor insulation, this shear-head screw only operates as pure pressure screw, and prevents cutting of single conductor strands. 19

20 Ring Connector with Coated Aluminium Housing Wedge type A 4-Core Cable Cross Section [mm²] Ring Connector Contact Screw Mains SM 95 SE Branch maximum outer diameter Dimensions [mm] Mains Branch width length of diameter of screw screw with shear head socket screw radial R tangential T SW(i) (DIN 475) torque [Nm] Wedg es Number 6-35 SM 50 SE A SE 150 SM 6-70 SM(r) 95 SE(r) A Explanation cross sections: S=sectorial, E=solid, M=stranded, (r)=rounded This ring connector was designed for installation in mountainous areas with great altitude differences (inclines). In such cable systems water that has entered the cable would cause considerable hydrostatic pressure in service joints. Above type is able to withstand this extreme strain because of the additional insulating special coating of the aluminium housing. 20
