Riyadh Lv Cable Catalogue Pdf 36 [BEST]


Southwire SIMpull THHN copper conductors are primarily used in conduit and cable trays for services, feeders and branch circuits in commercial or industrial applications as specified in the National Electrical Code. Voltage for all applications is 600 volts. SIMpull THHN copper conductors are designed to be installed without application of a pulling lubricant. These conductors have multiple ratings. Depending upon the product application allowable temperatures are as follows:

The voltage drop of any insulated cable is dependent upon the route length under consideration (in meters), the required current rating (in amperes) and the relevant total impedance per unit length of the cable. The maximum impedance and voltage drop applicable to each cable at maximum conductor temperature and under a.c. conditions is given in the tables. For cables operating under dc conditions, the appropriate voltage drops may be calculated using the formula.


Consider a 3 phase systemThe requirement may be for a load of 1000A to be transmitted over a route length of 150m, the cable to beclipped to the wall and close protection provided. The rating tables in the IEE Regulations indicate that a35mm copper conductor PVC SWA PVC cable would be suitable for the loading required, but the voltage dropmust be checked.


ConverselyThe user may have 150m of 35mm (Cu.) multicore PVC cable and require to know what maximum currentrating can be applied without exceeding the allowable voltage drop. The method is exactly the same as above,viz:total drop = 16.6


IMC has many advantages. It works with all conventional motor technologies, with closed loop or open loop control, and offers sensor less homing with torque detection. Drives are adapted to the applications through simple parameterization. This means that knowledge of servo technology or programming languages is not required. As no encoder or additional cables are needed, engineering, installation and commissioning time and costs can be reduced.
