Concentric Cables
Concentric Cable.
Application: Primarily used in overhead service for attachment to the side of a building from the weatherhead to the meter equipment; maximum conductor temperature of 75; maximum potential of 600 volts. Also may be used as branch circuit or feeders for wiring of ranges, wall-mounted ovens, counter-mounted cooking units and clothes dryer circuits where the a-c supply is not over 150 volts to ground Cable Specification: Split Concentric Cable available is sizes 4mm to 35mm and manufactured to British Standard BS7870. The cable features plain annealed stranded copper phase conductor, XLPE insulated surrounded by a concentric layer of plain annealed solid copper neutral conductors. XLPE insulated and plain annealed solid strand bare copper earth conductors, PVC outer sheath. Black. 600/1000 volts grade to BS7870. Conductor: Plain Annealed Stranded Copper Phase Conductor. Insulation: XLPE insulated surrounded by a concentric layer of plain annealed solid copper neutral conductors. Armouring: XLPE Insulated and Plain Annealed Solid Strand Bare Copper Earth Conductors Sheath: PVC Sheath Colour: Black Voltage Rating: 600/1000 Volts
STANDARD:IEC60228 VOLTAGE:600/1000V CAPACITY:2000km/month Flexibility for easy handling Excellent moisture resistance Reduced overall diameter for tight duct applications without reducing insulation wall Available with EPR Insulation
1.Solid or stranded copper/aluminum conductor 2.Insulation with XLPE, PE, or PVC 3.For cables of two-phase or three-phase conductors, round or flat shape available 4.PVC inner COVERING 5.Concentric layer of helically layed copper/aluminum wires 6.Wrapping tape 7.Black XLPE, PE, or PVC jacket The concentric cable is used in electric service entrance from the power distribution network to the meter pannel(especially where it is required to prevent electricity theft), and as feeder cable from the meter pannel to the distribution pannel. This cable an be used in dry and wet places, outdoors or directly buried. It has a maximum operating temperature of 90�ºC and rated voltage of 600V&below.
