Why is the temperature of an electric cable important?
Why is the temperature of an electric cable important?
This oversight is important especially for power circuits because the temperature index of the cable (the temperature at which the cable material will self-support combustion in normal air) will be significantly affected by its starting temperature i.e.: The hotter the cable is, the more easily it will propagate fire.
How does a temperature control system control temperature?
To accurately control process temperature without extensive operator involvement, a temperature control system relies upon a controller, which accepts a temperature sensor such as a thermocouple or RTD as input. It compares the actual temperature to the desired control temperature, or setpoint, and provides an output to a control element.
How does a temperature controller work outside the band?
Outside this band, the controller functions as an on-off unit, with the output either fully on (below the band) or fully off (above the band). However, within the band, the output is turned on and off in the ratio of the measurement difference from the setpoint.
What is the General Cable cable installation manual?
Welcome to the ninth edition of General Cable’s Cable Installation Manual for Power and Control Cables. This manual provides installation information for power and control cables for industrial.
What should minimum temperature be for cable installation?
Minimum Installation Temperature. This is the lowest installation temperature recommended by the cable manufacturer for a given wire or cable. This temperature is usually 10 to 20° C warmer than the laboratory cold bend temperature rating to compensate for the higher mechanical forces often encountered during installation.
Do you need a temperature controller for a cable heater?
The cable will draw a lot of energy trying to get to its top-out temperature, unless you add a temperature controller. A controller doesn’t have to be extremely costly, though. If you’re running cable on DC, we recommend the SoliStat™, which doesn’t burn out like most thermostats do when applied to DC circuits.
What does the temperature rating on a cable mean?
Temperature Ratings. This is the temperature rating that most cable users think of first. It is usually defined as the maximum continuous temperature that the wire can withstand during its lifetime. It is generally limited by the thermal aging characteristics of the polymers, i.e., the plastics used to insulate and/ or jacket the wire.
How does temperature affect your Ethernet cable products?
Ethernet cables specifically balanced twisted pair cables used in various applications are created to operate in various environments. They have special insulation materials and jacket materials that help them achieve performance in conditions such as lower and hotter temperatures.
