Magnitude and duration of possible load Voltage drop Mode of installation, either underground or in air Chemical and physical properties of soil Max. Construction and tests are in accordance with the recommendations of IEC or BS publications where applicable. Weights and Dimensions Weights and dimensions characteristics are approximate and any deviations are due to manufacturing tolerance. Jacket Marking Standard embossed outer jacket marking consisting of: 1.
Type designation, size of conductor, rated voltage 3. Continuous length marking every meter 6. Nominal value Value by which a quantity is designed and which is often used in tables. Approximate value Value which is neither guaranteed nor checked; It is used, for example, for the calculation of other dimensional values. Median value When several test results have been obtained and sorted in an ascending or descending order, the median value is the middle value if the number of available values is odd, and the mean of the two middle values if the number of available values is even.
A of IEC Type tests Tests made before supplying on a general commercial basis, a type of cable covered by this standard, in order to demonstrate satisfactory performance characteristics to meet the intended application. These tests are of such a nature that, after they have been made, they need not be repeated, unless changes are made in the cable materials or design or manufacturing process, which might change the performance characteristics. Electrical tests after installation Tests made to demonstrate the integrity of the cable and its accessories after installation.
Power Cable Power cables are mainly used for power transmission and distribution purpose. It is an assembly of one or more individually insulated electrical conductors, usually held together with an overall sheath. The assembly is used for transmission and distribution of electrical power. Electrical power cables may be installed as permanent wiring within buildings, buried in the ground and run overhead or exposed. Bare Overhead Conductor Bare Overhead Conductors are used in overhead transmission and distribution network applications. They are also used for un-insulated hook ups, jumpers, grounding conductors and other applications.
