DATA FLEX CABLES WITH DOUBLE SCREENING

Data transmission cables transmit signals of extremely varied types with absolute accuracy.

We offer you various types of Data transmission cables used for varied operating conditions i.e. For high data transmission rates, for flexing applications or for specific of signals.

Our range includes unscreened /screened with Aluminium backed mylar tape with sufficient over lapping or annealed tinned copper briding. double screened cables, cables twisted with long and short lay length and twisted with overall screened pairs reduced crosstalk in lower and medium frequency band. Double sreened (Individual and Overall) cables reduce crosstalk in all frequency bands, Co-axils cables are for high and very high signals frequency.

Primary function of data transission cables of any kind is to forward signals to the reciever with absolute signal integrity. Since the enviornment is full of interferences noise signals which are transmitted by electromagnetic fields, electrical and magnetic alternating fields, following rules must be taken into consideration which signal being transmitted uncorruptedly.

• Ring cabling should be avoided.
• Cables should be laid close to any metal housing
• Screens must be earthed at the point at which cables pass through panels.
• Cables with same interferences levels should be laid next to each other while cables with different interference levels should be laid well a part.

Dataflex Twisted Paired Data Transmission Cable is ideally suited when space constraints allows little space for insulation of cables and wires. When transmission distances are short and bending radius's small since only low currents are to be trnasmitted it is possible to use small cross-sections and top priority is high flexibility of cables.

Twisted pairs reduces electrical crosstalk between adjacent cores within the cable and highly flexible PVC based outer sheath makes cables resistant to mechanical & chemical damage.

Description :

Fine wire strands of Annealed plain/tinned high conductivity electrolytic grade copper conductor. Individual core insulated with extruded PVC compound. Two such cores twisted together to from a pair, all such pairs laid up in a common covering of PVC and finnaly jackted with extruded PVC (special type)

Armouring will be of S.S. braiding or galvanised mild steel wire/strip.
