Who we are Cavotec is a multi-national group of companies serving the following industries: mining and tunnelling, ports and maritime, steel and aluminium, energy and offshore, airports, general industry and automation. In the early 1960’s our main focus was the design and production of motorised cable reels primarily for manufacturers of tower cranes, harbour cranes and mining equipment. Today, Cavotec is connecting mobile equipment around the world in many diverse applications. Where we are The Cavotec Group consists of 7 manufacturing “Centres of Excellence” located in Canada, France,...

Flexible power and Table 2: Minimum bending radius Bending radius and overall diameters Precise calculation of the bending radius is a determining factor for cable reliability. A decrease in minimum bending radius has a major effect on the life of a cable because it causes stretching and internal distortions. Another important factor is the frequency of the cable movements. If movement is slow and infrequent a tighter bending radius can be considered. Special attention should be taken for installations with pulleys or guide-rollers. Special attention should also be paid to installations...

8 • Flexible power and control cables Other systems of cable movement The systems most frequently employed are perhaps cable tender systems, pulley systems and cable chains. The first two systems involve high tensile stress whereas the third on a whole does not. Particular attention must be paid to the minimum bending radius and to the distribution of loads between the cables and cable tenders. Cables with a greater cross section should bear the loads and not the control cables that may be present. Guide pulley and anchoring devices. When designing these components, care must be taken to...

10 • Flexible power and control cables Voltage drop The voltage drop should not only be checked for low voltage but also for medium voltage applications. The value is calculated by multiplying the factors K (mV/Am) given in table 5 with the current capacity I (A) of the cable and by the length of the connection L (km). This calculation is valid with sufficient approximation for all voltages where: conductor temperature = 80C; cos 0,8; frequency = 50 Hz. Voltage drop (V) = I(A) x L (km) x K(mV/Am). The factors have been calculated using the formula: K(mV/Am) = 1,73 x (R cos X sen j) where:...

Flexible power and Thermal limit in case of short circuit In accordance with VDE Standard 0250 c. 8/75 the admissible thermal limits for short circuit current in heavy cables must be calculated using the following reference values: • Initial temperature: 80°C (cable under full load) • final short circuit temperature: 200°C The short circuit currents (thermal limit) given in table 6 have been calculated using these reference values and are valid for a base time of 1 second. For other time periods, taking into account the protection characteristics of the machine, the value in the table must...
