Ì Increased armour conductivity by insertion of hard drawn copper wires in armour. ▓ Cable Construction Caledonian medium voltage cables are manufactured using the monosil process. Caledonian provides the highly specialized plant state-of-the-art research facilities and meticulous quality control procedures that are required for the manufacturing of PVC insulated cables for use up to 6KV and XLPE/EPR insulated cables for use at voltages up to 42 KV. The materials are all kept in cleanliness-controlled conditions throughout the production process in order to ensure the absolute homogeneity of the fnished insulation materials. Conductors Either aluminium or copper conductors are used. Conductors up to 800mm² will be circular compacted stranded and shall comply with IEC 60228 class 2. 1000mm² conductor will be circular stranded type on which a layer of semi-conducting tape will be applied. Conductor Screen This will be an extruded layer of semi-conducting crosslinkable compound applied under simultaneous triple extrusion process over the conductor along with the insulation and the insulation screen. The triple extrusion is a single high precision operation that eliminates the possibility of any contamination between the layers which could create irregularities in the electrical field. By careful material selection and special attention to process parameters Caledonian produces the insulation screen layers with the required degree of stripping force as stipulated by the applicable national or international standard.

33 www.caledonian-tech.com www.caledonian-tech.net Medium V oltage Cables to IEC 60502 Insulaton Screen: The insulation screen consists of an extruded layer of non metallic semi- conducting compound extruded over the insulation. The extruded semi-conducting layer shall consist of bonded or cold strippable semi-conducting compound capable of removal for jointing or terminating. As an option a semi-conducting tape may be applied over the extruded semi-conducting layer as a bedding for the metallic layer. The minimum thickness is 0.3 mm and the maximum resistivity is 500 Ohm-m at 90°C. The screen is tightly ftted to the insulation to exclude all air voids and can be easily hand stripped on site. The insulation screen is not necessary for both PVC and EPR/HEPR insulated 1.8/3KV and 3.6/6KV cables. The screen may be covered by semi-conductive water blocking swellable tape to ensure longitudinal watertightness. Metallic Layer: The metallic layer may be applied over the individual cores or the core assembly collectively. The following types of metallic layers are provided: 1 Metallic Screen 2 Concentric Conductor 3 Metallic Sheath 4 Metallic armour The metallic screen shall consist of either copper tapes or a concentric layer of copper wires or a combination of tapes and wires to provide an earth fault current path. The concentric conductor is applied directly either over the insulation or over the insulation screen or over an inner covering. The metallic sheath consists of lead or lead alloy applied as a tightly ftting seamless tube. The metallic armour consists of either fat wire armour round wire armour and double tape armour. Table 2.

Caledonian Medium V oltage Cables Three Core Cables to IEC 60502 ▓ APPLICATIONS: The three core cables are designed for distribution of electrical power with nominal voltage Uo/U ranging from 1.8/3KV to 26/35KV and frequency 50Hz. They are suitable for installation mostly in power supply stations indoors and in cable ducts outdoors underground and in water as well as for installation on cable trays for industries switchboards and power stations. ▓ STANDARD: IEC 60502 Part 11.8/3KV IEC 60502 Part 23.6/6KV to 18/30KV ▓ CONSTRUCTION: Conductor: Plain annealed copper or aluminium complying with IEC 60228 class 1 or 2. Conductor Screen: The conductor screen consists of an extruded layer of non metallic semi-conducting compound applied on top of a semi-conducting tape. The conductor screen is applied under triple extrusion process over the conductor along with the insulation and the insulation screen. The extruded semi-conducting compound is frmly bonded to the insulation to exclude all air voids and can be easily hand stripped on site. The conductor screen is not necessary for both PVC and EPR/HEPR insulated 1.8/3.6KV and 3.6/6KV cables.

The extruded semi- conducting layer shall consist of bonded or cold strippable semi-conducting compound capable of removal for jointing or terminating. As an option a semi-conducting tape may be applied over the individual cores or core assembly as a bedding for the metallic layer. The minimum thickness is 0.3 mm and the maximum resistivity is 500 Ohm-m at 90°C. The screen is tightly ftted to the insulation to exclude all air voids and can be easily hand stripped on site. The insulation screen is not necessary for both PVC and EPR/HEPR insulated 1.8/3.6KV and 3.6/6KV cables. The screen may be covered by semi-conductive water blocking swellable tape to ensure longitudinal watertightness. Inner Covering Fillers: For cables with a collective metallic layer or cables with a metallic layer over each individual cores with additional collective metallic layers semi-conducting inner covering and fllers shall be applied over the laid up cores. The inner covering and fllers are made of non hygroscopic material like polypropylene except if the cable is to be made longitudinally watertight. The inner covering is extruded in general but may be lapped if the interstices between the cores are flled. The approximate thickness of extruded inner coverings is given in Table 2: Table 2.

Metallic Layer: The metallic layer may be applied over the individual cores or the core assembly collectively. The following types of metallic layers are provided: 1 Metallic Screen 2 Concentric Conductor 3 Metallic Sheath 4 Metallic Armour The metallic screen shall consist of either copper tapes or a concentric layer of copper wires or a combination of tapes and wires. The concentric conductor is applied directly over the inner covering. The metallic sheath consists of lead or lead alloy applied as a tightly ftting seamless tube. The metallic armour consists of either fat wire armour round wire armour and double tape armour.

Caledonian Medium V oltage Cables Technical Information ▓ Current Ratings The current ratings given on the previous pages are based on the standard conditions of installation detailed bellows: Maximum conductor temperature: 90°C Maximum ambient temperature: In air 30°C In ground 20°C Ground thermal resistivity: 1.5K•m/W Laying depth: 0.8m Spacing between cable laid: In fat formation 2 times of cable overall diameter In trefoil With cable touching Where the site conditions differ from the standard conditions mentioned it will be necessary to multiply the tabulated ratings by the actors given in the following tables. These factors are for variation in ambient ground temperature soil thermal resistivity and depth of laying. Where more than one circuit is installed in close proximity then will be necessary to derate further in accordance with the group rating factors given. ▓ Rating Factors Cables laid direct in ground: Variation in ground temperature Ground Temperature 15 20 25 30 35 40 45 Cabe Type Rating Factor All Cables 1.00 0.97 0.93 0.89 0.86 0.82 0.76 Rating factor for depth of laying To center of cable or trefoil group of cables Depth of laying 1.9/3.3KV 1.8/3KV to 19/33KV 18/30KV Cables m Up to 300 mm² Above 300 mm² 0.50 - - 0.60 - - 0.80 1.00 1.00 1.00 0.98 0.97 1.25 0.96 0.95 1.50 0.95 0.94 1.75 0.94 0.92 2.00 0.92 0.90 2.50 0.91 0.89 3.00 or more 0.90 0.88
