What is the conductor types in cables ?

1. What is the CONDUCTOR?
It is an insulated or uninsulated wire or bundle of wires and consisting of one or more wires, used to transmit electrical energy.

2. What are the materials used in CONDUCTOR?
The material should be selected according to the usage and purpose of the cable.

Generally;
Low voltage indoor installation cables: Copper,
Low voltage and medium voltage energy cables: Copper or aluminum,
High voltage underground and submarine cables: Copper or aluminum,
High voltage overhead line cables: Steel-core aluminum conductors are used.



National standards were canceled and EN standards were published instead.
Within this scope, national standards of TS 2, TS 16, TS 17 and TS 18 were canceled in Turkey and TS EN 13602 standard has been published instead.
Generally, it is recommended to use Cu-ETP type copper in energy cables and Cu-OF type copper in signal and communication cables.

The physical properties of copper wires are defined in Table 2 of EN 13602.







3. What are the types of CONDUCTOR?

Copper conductors used in energy cables are generally manufactured according to         IEC 60228 standard or they are manufactured according to national standards prepared by reference to this standard.
TSE translated this standard into Turkish and publishedwith the number of TS EN 60228 in 2005.
Conductors are divided into 4 categories for the purpose of use;


    Class 1: Solid conductors,
    Class 2: Stranded conductors,
    Class 5: Flexible conductors,
    Class 6: Conductors with flexibility more than Class 5


Class 1 (Solid conductors):
They are manufactured as bare or metal coated, from round single wire and generally in the range of 0.5-16 mm² for the intended use.


    Which cable types have Class 1 conductors?

H05V-U, H07V-U, H05Z1-U, H07Z1-U and conductor cross section ≤16mm2 of NVV, YVV, YVCV, YVZ2V, NHXMH, N2XH, N2XCH, N2XRH, YXV, YXCV, YXZ2V type cables are manufactured with Class 1 conductors, unless if there isn't any different demand.



The values of maximum DC resistance and maximum conductor diameter are specified in Table.1 and Table C.1. in TS EN 60228.






    What are the main properties of Class 2 conductors?
    Compliance with the largest DC resistance as defined in Table 2,
    Compliance with the minimum number of wires as defined in Table 2,
    Compliance with the largest conductor diameter wires as defined in Table C.1.




    Why are Class 5 conductors called F or K?

F - Cables that are allowed for moving use,
K - Cables that are not allowed for moving use.


    What are the main properties ofClass 5 and Class 6 conductors?
    Compliance with the largest DC resistance as defined in Table 3 & 4,
    Compliance with the minimum number of wires as defined in Table 3 & 4,
    Compliance with the largest conductor diameter wires as defined in Table C.1.
