What are the advantages of using ProPlex data cables with FEP insulation?
- SUPERIOR ELECTRICAL PROPERTIES. Due to the stability of the low dielectric constant, FEP insulation has the excellent electrical properties required for cables that carry high-speed data.
- CONSISTENT PERFORMANCE. Using additives in an insulating material may lead to inconsistent performance due to variability in manufacturing. FEP requires NO additives to meet signal performance for low capacity and low loss.
- UNEXCELLED FIRE SAFETY PROPERTIES. Remarkable resistance to high temperature and flames because of very high melting points and auto–ignition temperatures, as well as exceptional thermal degradation thresholds. Flame propagation characteristics, such as the rate of heat release and smoke generation, are all very low.
- LONG SERVICE LIFE. Outstanding retention of properties after aging, even at high temperatures and in the presence of solvents, oils, oxidizing agents, ultraviolet light, and other environmental agents. Since there is no use of degradable stabilizing additives, FEP offers an important safety advantage when designing products for long service life.
- WORKING TEMPERATURE. The working temperature for permanent operation of FEP is Minus 100 Degree Celsius to plus 200 Degree Celsius. The melting point of FEP is plus 290 Degree Celsius.
What is the correct wiring for 4-pin XLR cables?
It depends on what they're being used for. While some color changers and fixtures use the same cable and connectors, there are wiring differences that should be followed to avoid adverse effects or damage to units.
What's the difference between a Fan-out & a Break-out?
Nothing, they're the same thing. These terms apply to a cable assembly which distributes control or load circuits "out" of a Multicable carrying multiple circuits. It typically comprises a multipin connector wired with several individual cables, one for each circuit.
Can I terminate my multicable directly to stage pin connectors or do I have to always use a breakout?
No: The conductors of Multicables used in stage lighting load distribution are not designed to be "splayed out" to multiple connectors, doing this could be dangerous. A breakout assembly or some kind of transition device should always be used.
Can you use mic cable for DMX?
No: DMX is a digital control signal (RS485) that needs a true, low-capacitance, control cable. Although mic cable wired to 5-pin XLR connectors may seem to work OK, there is a great danger that there will be problems, when you expect them least. We would say you should use the best possible cable, so that when problems do arise with your DMX equipment, you can eliminate the cable as the cause of trouble.
Can I use 2/0 cable for dimmer pack feeders?
Yes, as long as the type of cable used is approved for such use and the dimmers are not drawing more than the rated current carrying capacity. The feeder cables typically used in the US' Entertainment industry, Types SC and W, have a 290 Amp rating for size 2/0.
What's with the knots in the sash cord on feeder cables in the film industry?
Feeder cables are designated with colored tape and often have knots tied in #8 sash cord at the ends of the cables. The code is as follows:
|Hot 1||Black||Two knots on one side of sash cord|
|Hot 2||Red||One knot on one side of sash cord|
|Hot 3||Blue||No knots on sash cord|
|Neutral||White||One knot on each side of sash cord|
|Ground||Green||Two knots on each side of sash cord|
