Shielded Cables
Chetan Shielded cable ensures signal integrity and provides confidence in audio and video transmissions, preventing downtime and maintaining sound and picture clarity. Among the shield types available are braid shield, foil shield, combination shields and lapp shields.
Braid Shield: Braid shield consists of groups of tinned or bare or silver plated copper or aluminium strands, one set woven in a clockwise direction and interwoven with another set in a counter clockwise direction.
Braid shields provide superior structural integrity, while maintaining good flexibility and flex life. These shields are ideal for minimizing low frequency interference and have lower DC resistance than foil. Braid shields are effective at audio, as well as RF ranges. Generally, the higher the braid coverage, the more effective the shield. However, the trade-off between cost and braid coverage must be considered. Typical braid coverage are between 80 and 95%. Coverage of 100% is unattainable with a braid shield.
Foil Shield: Foil Shield consists of Aluminium Foil laminated to a polyester or Polypropylene film. The Film gives the shield mechanical strength and bonus insulation. Foil shield provides 100% cable coverage, necessary for electrostatic shield protection. Because of their small size, foil shields are commonly used to shield individual pairs of multipair data cables to reduce crosstalk. Drain wires are used with foil shield to make termination easier and to ground electrostatic discharges. The shortcoming in using the foil shield include higher DC resistance and lower mechanical strength than braid or spiral shield.
Lapp Spiral Shield: A spiral shield consists of wire usually copper wrapped in a spiral around the inner cable core. Superior flexibility and flex life, ease of termination and upto 97% coverage are the advantage of spiral shields. They are best suited for audio applications. As a rule spiral shields are not suitable above the audio frequency range due to coil effect produced by the inductance of the spiral wire strands.
Combination Shields: These consisit of more than one layer of shielding. They provide maximum shield efficiency across the frequency spectrum. The combination foil/Braid shield combines the advantage of 100% foil coverage plus the strength and low DC resistance of the braid.
