Single Core & 3 Core Cable Singapore

single-core-cablePower cables can come in different core combinations that will vary depending on the purpose they are intended to serve. A twin core and earth cable have a bare copper earth conductor between two cores made from insulated solid copper. The bare earth conductor will be fitted with a green and yellow sleeve during the installation process to comply with the regulations in Singapore and internationally. The 3-core and earth cables have three inner solid copper cores that are insulated, and a bare earth conductor made from copper positioned between the copper cores. Similar to the twin core and earth cable, the bare earth conductor in the 3-core and earth cable will be fitted with a green-and-yellow sleeve.

3 Core Cable SingaporeIn instances where the duct size is too small, single core cables are usually preferred. Other circumstances where a single core conductor is ideal are when longer cable runs are required between the joint bays, or within the limited space in a termination box. During the above situations, a trifurcating joint can be used to transition from one type of cable (3-core cable) to another (single core cable). Single core cables are usually used in lighting and power circuits in both commercial and domestic applications, and in the internal wiring of appliances.
