Shield braiding - Import export

Shielding braids consist of bobbin wires, located parallel, which have been braided into a tube. Manufactured from Cu-ETP1, Cu-OF1, LEONI-Histral®-alloys (upon request), aluminium and stainless steel, with coating in bare, tin-plated, nickel-plated or silver-plated, hard or soft annealed. Sinlge-wire diameter ranging from Ø 0.10 mm to Ø 0.40 mm. Cross-section ranging from 0.25 mm² bis 400 mm². Tubular shielding braid is smoothly expandable and has a very good shielding effect. The couverage can be determined precisely by changing the braiding angle. Suitable for electrical and mechanical shielding of wires, cables, cable bundles and cable harnesses.

The new UNI Dicht TRI achieves the highest shielding attenuation values over the complete frequency range and convinces with a very high current carrying capacity for the reliable discharge of undesirably high shielding currents. The installation is simple and safe: only the cable sheath has to be removed at the contact point where the shielding braid is to be contacted. As soon as the cable is inserted into the cable gland, the TRI spring makes reliable contact with the cable shield, even in the case of non-circular or off-centre cables. In any case, this type of contacting from PFLITSCH means that the cable shield does not have to be exposed until directly at the connection point in the control cabinet. Because the shielding braid remains 100% intact, maximum shielding attenuation is achieved and the useful signals are transmitted without unnecessary interference from noise signals.

The increasing spread of electromagnetic radiation and the greater sensitivity of modern electronic components mean cable glands have an important role to play in a system's screening concept. PFLITSCH offers a graduated selection of EMC capabilities in its UNI Dicht and blueglobe cable glands for use in EMC applications up to Cat. 7A. The EMC cable gland blueglobe TRI separates the functions of sealing and EMC screening and therefore achieves the highest attenuation values of 80 dB up to 100 MHz. Even in the frequency range up to 2.5 GHz, the values are typically at least 50 dB. High current-carrying capacity is also provided. A triangular spring fits around the cable's braided shielding. The design of the spring precludes its getting caught in the braiding if the assembly is dismantled.

Round copper wire made from Cu-ETP1, Cu-OF1 and LEONI Histral® alloys, in bare, tin-plated, nickel-plated and silver-plated, soft annealed. Single wire diameter ranging from Ø 0.05 mm to Ø 0.254 mm. Number of wires used for strands: between 2 and 16 (subject to single-wire diameter). Single wire or multi wire on special bobbins fit for use in braiding machines. The braids manufactured by these machines are used in cables and conductors geared towards electromagnetic shielding or protection against damage as well as serving as a reinforcement.
