High voltage cables –
The arteries of the power grid ABB offers high-voltage power cable cords systems for underground and submarine applications. We design, produce and install polymeric insulated cables for direct current (DC) or alternating current (AC) and oil-impregnated, paper-insulated cables for DC. Combined with ABB’s cable accessories they form a reliable Power cable cords system with a very long service life. Cable systems from ABB can be found all over the world, transmitting power between countries, connecting offshore wind farms and oil/gas platforms to mainland grids and feeding power into major cities.
Customer value –
Our response the basic requirement from our customers is to have a connection from A to B – with minimal environmental impact and low losses. ABB can offer many degrees of involvement base on the customer’s needs. It could be assisting during the pre-engineering phase or making preparative studies of the Power cable cords grid in order to design and offer the best solution. ABB can offer turnkey systems and project management or just cables, accessories, or installation of the cable system.
Distribution wire & cable –
Focusing on the supply of overhead power distribution lines and underground power distribution cables, Group of Electric Company is contributing to the construction of power distribution networks for the reliable supply of electricity to demand centers. We manufacture and deliver a broad range of power cable cords tailored to different installation conditions, satisfying the diverse needs of our customers.
Industrial cables –
Cabtire cables for power supply and the control of heavy machinery must feature high reliability and the ability to withstand severe mechanical loading. Group of Electricity Company has been supplying these cables for 30 years, since it developed and found practical application for cabtire cable TraCab. We have been particularly successful in pioneering the use of a fiber-optic composite cabtire cable.
Remember that hazardous conditions may also exist on low-voltage outputs where high power is possible (>240 VA). As a minimum, effective current limiting may be required. The power supply should also be able to withstand an overload test consisting of blocking the air vents, stopping the fan, and overloading or shorting the output until the condition becomes stabilized or the ultimate result is achieved. Failure would certainly include flame and smoke, excessive heating of components, flying shrapnel from an exploding component, or failure to pass an appropriate HiPot test. The design must also ensure that no single failure causes any of the above hazardous conditions. The safety engineer randomly and selectively opens or shorts any component with flame-detecting cheese cloth draped around the unit under test. Anticipating these tests and designing for them is a necessary task.
There are several low resistivity (or high conductivity) metals that may be used as conductors for power cable cords. Examples of these as ranked by low resistivity at 20°C are shown in Table.
