2 conductor round cable 2 conductor twisted cable
in 4 core cable all four cables are equal dia and in a 3.5 core cable 3 cores are equal dia and fourth one will be with half dia. and it is used for neutral in 3phase 4 wire syastem
A two core cable is used where an earth is not required. A three core cable is used where an earth is requred. Specialised three core cables are available for 3 phase and two-way switching applications.
A single core cable means it has one wire going through the outer casing.Like a 3 pin plug has 2 or 3 which are (blue)-Neutral,(Brown)-Live and maybe (Green/Yellow)-Earth which would be 2 or 3 core.
The term core represents each individual conductor within a cable, and a pair is two cores (or two conductors) within a cable. For example if you have a 3 core cable, then the cable has 3 separate conductors in it (3 separate cables within the PVC coating). A 3 pair cable would be 3 sets of 2 cores, so this would have 6 conductors within the cable.
To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
Core Flex = one conductor per cable Tech cable = 3 conductors per cable
Yes. remember that one core is with reduced size by half.
The plastic core keeps the twisted pairs separated allowing less crosstalk than CAT-5 cable.
Assuming you're taking about 'twin core and earth' cable - it's commonly used to supply power to high-current devices such as cookers and immersion heaters.
