The National Standard for Rehearsal Cables is a standard for cables used to connect audio, video, lighting and other equipment during performances, shows, concerts and other events. These cables are widely used in the field of stage performances and acting to ensure reliable connection and signal transmission between equipment. Here are some of the standards for rehearsal cables and their importance. Standard length: rehearsal cables usually come in standard lengths to accommodate various stage settings. Typically, the standard lengths are 30 meters, 50 meters, 75 meters or 100 meters. This facilitates stage setup and equipment arrangement while ensuring signal quality and stability. Signal Transmission Quality: The standards for rehearsal cables have clear requirements for signal transmission quality. They should be able to transmit high-quality audio and video signals and reduce signal interference and attenuation over long distances. This can be achieved through the use of high-quality wires, shielding and connectors. Electrical Parameters: National standards for color cable usually specify electrical parameters such as resistance, capacitance and inductance. These parameters are critical to the stability and consistency of signal transmission. Color cable that meets international standards should have appropriate electrical parameters to ensure the reliability of the signal during transmission. Safety Requirements: Since color cable is often used on stage, safety is a very important consideration. The national standard of color line cable usually stipulates the requirements of fire resistance, abrasion resistance and voltage resistance of the cable to ensure that no fire, electric shock or other safety accidents will occur during the use. Marking and packaging: The national standard for colored cable also specifies the marking and packaging requirements for cables. The cables should be clearly marked with information such as model number, length, date of production and manufacturer for user identification and traceability. In addition, the packaging should be strong enough to prevent damage during transportation and storage. Durability and Reliability: Color cable often needs to withstand frequent plugging, unplugging and movement, so durability and reliability are also important elements of the national standards for color cable. These standards usually specify parameters such as the mechanical strength, abrasion resistance and tensile strength of the cables to ensure that the cables do not break or otherwise fail during prolonged use.
