They arent. Most are either 2 or 4 conductor.
EDIT: Telephone cables in the UK consist of either four or six-core cable - depending on the circumstances of the installation. Each strand of the cable is a single wire wrapped in a colour-coded sheath to aid identification. The reason each wire is only a single strand, is because the current used to power the phone-line is extremely small, so doesn't need multi-stranded cable. (Snakester1962)
What else can I help you with?
Is RNA always single stranded?
No, RNA is not always single stranded. It can exist as single stranded or double stranded depending on its function and structure.
Is RNA double stranded or single stranded?
RNA is typically single-stranded, unlike DNA which is double-stranded.
Can a telephone cable be used in place of a network cable?
No. Telephone cables have a different kind of connector. Networking cables (also known as Ethernet cables) are also a bit wider then telephone cables.
Is tRNA single-stranded?
Yes, tRNA is single-stranded.
Which molecule is always single stranded?
RNA is always single stranded. DNA, on the other hand, can exist as either single-stranded or double-stranded.
Is DNA or RNA single-stranded?
RNA is typically single-stranded, while DNA is double-stranded.
Is RNA double or single stranded?
RNA is typically single-stranded, unlike DNA which is double-stranded.
Are plasmids single or double stranded?
Plasmids can be either single or double stranded, but most commonly they are double stranded.
What has the author Louis Casper written?

WHY STRANDED CONDUCTERS ARE USED IN POWER CABLES?
Stranded conductors are more flexible than solid conductors.
Is astrovirus single or double stranded?
single stranded RNA (positive sense)
Is the DNA in a virus typically single stranded or double stranded?
The DNA in a virus can be either single-stranded or double-stranded, depending on the type of virus.
