Instrumentation Cables
9 KEWBERG manufactures and supplies a wide range of Instrumentation cables, which are made using superior raw materials. These are extensively used in data acquisition systems, process control and computer networking, public address systems and digital control, measuring & communication systems. We manufacture and stock a comprehensive range of Screened, which are used in signalling systems, control and instrument circuits. These Cables also report and monitor process variables ranging from transducers to environmental controls and computer inputs. Maximum rejection of electromagnetic noise is achieved by twisting the insulated conductors. Twisting causes the noise to be cancelled in adjacent sections of the wire. Maximum electrostatic noise rejection is achieved by shielding the cable with aluminium foil tape. A minimum of 5% overlap of the shield ensures % coverage even when the cable is flexed. The drain wire under the shield provides continuous low resistance path to ground and simplified hook-up at grounding terminals. These Cables can also be provided with aluminium polyethylene laminate (APL) and steel wire armouring (SWA). Ease of installation is another major benefit of these Cables. Individual cores, pairs, triads or quads are colour coded and or number printed. A pair of Communication Wires can also be provided. The Cables are available in a wide range of insulation and jacket materials, the most popular being PVC, Polyethylene, FR PVC, LHcL PVC or HFFR PVC.
Conductor Bare (plain) or tinned electrolytic annealed copper conductor. Solid, stranded or flexible. Insulation Either XLPE, PVC or PE insulation in accordance with SABS as required. Twisting and Laying Required numbers of cores are laid up in case of multi-core core cables. Individual pairs, triads or quads are formed by uniformly twisting the insulated cores with required lay lengths, prior to laying. Core Identification Cores can be colour coded or number printed for easy identification. In case of multi pair cables both cores in each pair is alpha numerically at short intervals, individual screens are also printed. Overall Screen After final lay up of the complete cable an overall screen of aluminium-polyester tape is applied along with sqmm multi stranded annealed tinned copper (ATC) drain wire in continuous electrical contact with aluminium side of the tape. Individual & Overall Screen Individual pairs, triads or quads are screened by aluminium-polyester tape along with sqmm annealed tin copper drain wire and overall screened by aluminium-polyester tape as mentioned above. Tinned copper braid screening can also be used for individual screen. In case of individually screened cables for critical applications an extruded isolation sheath can also be provided over the individual screens. Assembly Binder After final assembly PVC or PE is provided as required to act as a binder as well as bedding for the outer screening in all cables. Armour Galvanized steel wire or a flame retardant aluminium polyethylene laminate. Inner & Outer Sheath PVC, HFFR, LHCL PVC or FR PE sheath can be provided. U.V stabilized Polyethylene sheath can also be provided for hazardous areas. A blue colour outer sheath for intrinsically safe areas can be provided on request. A communication wires can be provided if desired. Rip Cord To simplify jacket removal, high tensile strength nylon Rip Cord is provided over laid up of pairs/ triads/quads below the outer sheath in case of unarmoured cable or below the Inner Sheath in case of armoured Cable. Quality Assurance Quality s are built in every Kewberg Cables product. Our cables are subjected to a series of required tests in our well-equipped laboratory. Besides the rigid tests and checks at every stage from raw material through manufacturing stages and finally up to the finished product. Being an ISO 9: certified company, our quality management standards conform to highest standards quality assurance practices.
