Instrumentation Cables Dealer, Distributor, Supplier & Stockist
Techno Flex is engaged in high quality Instrumental Cables. These
cables are available in different forms such as tried, paired, individual and
many more. Cables being offered by us are designed to offer interference free
transfer of data, security system and process control. These cables are mainly
used in the devices those are based on microprocessors. Designed with precision
these cables are manufactured to meet international quality standards. Products
manufactured by us are stringently tested to ensure the highest level of
quality. We use Aluminium Tape, Mylar and Polyester Tape & ATC Drain Wires to
ensure smooth and defect less communications.
General Instrumentation Cable
Conductor
annealed bare/ uniform coated with tinned/silver platted, high
conductivity, and electrolytic grade solid/stranded/flexible
conductor.
Insulation
conductor are insulated with general purpose pe / hr / frls / lszh / pvc
compound / or any other dielectric material as per customers
specification
Colour of dielectric :
cores are identified with different type of color scheme as per
requirement as below:-
- as per is:1554[pt-i]:88, 694:90.
- as per iec, itd or number printing.
- as per customers scheme.
Pair/triad/quad:
two/three/four cores are uniformly twisted together to form a
pair/triad/quad with maximum lay length 80 mm/as per requirement of
customer. The lay shall be so chosen as to minimize cross talk in the
cable.
Individual shielding :
if required, individual shielding may be of poly aluminum [thin layer of
aluminum foil bonded to polyester film] tape with annealed tinned copper
drain wire. It prevents the shorting of adjacent shield and minimizes
the cross talk and ground loops. A tinned copper drain wire is installed
to provide continuous contact with the shield and allow to connection to
ground. Tinning the drain wire reduces galvanic corrosion between drain
and shield.
Laying of pairs/triad/quad. :
pair/triad/quad are laid up with suitable lay. The outer most layers are
right hand lay and successive layers are laid up with opposite lay.
Then, a polyster tape is provided to bind up laid up pair/triad/quad.
Overall shielding :
if required, overall shielding may be of annealed tinned copper braiding
/ poly aluminum [thin layer of aluminum foil bonded to polyester film]
tape with annealed tinned copper drain wire. Braiding atc shield has
high tensile strength and provides better coverage in flexing
application. They are easier to terminate. This provides effective
shielding; cross talk and noise are kept to an absolute minimum.
Inner sheath :
the laid up pair/triad/quad after shielding are provided with an inner
sheath, which may be either extruded inner sheath or wrap with pvc
tape.
Armouring :
it is applied over inner sheath. It may consist of galvanized round
steel wires or galvanized flat steel strips
Outer sheath :
it is applied over armouring in case of armoured cable or over inner
sheath in case of unarmoured cable. The color of sheath is black or
grey. The sheath material may be general purpose/hr / frls / lszh pvc
compound as per requirement of specification.
Typical application :
for connection of instruments, process control systems, computers, data
transmission etc.
