UL 62 Soow 600V Flexible Rubber Portable Cord Cable

This is a term for the maximum current carrying capacity, in amps, of a particular device. The current carrying capacity is normally associated with electrical cable and is determined as the maximum amount of current a cable can withstand before it heats beyond the maximum operating temperature. The effect of resistance to current flow is heating and this is dependent upon the size of the conductor, the insulation material around the conductor, and the installation environment.The larger the con

Type tests (short for Prototype) are predominately destructive tests, conducted to determine if the cable construction and materials are compliant with standard specifications. As inferred in the name, prototype tests are done to prove design and the required cable parameters - they are only required to be done once and are generally not repeated. Examples of type tests include: Corrosive and acid gas Mass of zinc coating for galvanised wire armour Smoke emission Flame propagation test for multi

Cable size selection is based on three main factors: Current carrying capacity Voltage regulation Short circuit rating The current carrying rating is determined by the conductor size and the thermal heating of the cable. The cable spacing, application and insulation materials are relevant to the dissipation of this heat. Voltage regulation is not usually a problem with well-designed electrical power systems but the voltage drop incurred with excessively long cable runs needs to be accounted for.

There are several different types of cable gland and choosing the right one for your application is very important. When choosing a suitable compatible gland you need to consider the following: - The type of cable the gland will be connected to (for example SWA armoured cable requires a gland such as the BW brass cable gland) - The material the cable is made of, the construction and cross-sectional size (for instance, is the cable screened or braided?) - The colour requirement (if any) for the c

Intrinsic safety is a protection technique for the safe operation of electrical and electronic equipment in hazardous areas where any ignition source needs to be eliminated. Electrical cables are essentially sealed and so may be regarded as intrinsically safe in certain applications if protected from damage, external electrical or magnetic fields (EMI), and isolated from non-intrinsically safe circuits. The junctions and switches pose a potential hazardous ignition point in these environments an
