When materials heat up they expand.
When they cool down they contract.
If the telephone cable was made tight on a hot day, then they would get very very tight on a cold day, and would stretch (thus making them loose), or perhaps break. Repeated heating and cooling cycles would undoubtedly cause premature failure. Keep in mind that while you may see a large bundle of wires, the individual strands are quite small.
Also, the tension required to keep say a 50 foot or 100 foot stretch of wire from drooping is far greater than the tension required if it is allowed to droop a bit, thus you have less stress on the wires with a little sagging.
One final note. Copper is an excellent conductor, thus is commonly used for phone cables. But, it is heavy, and it is also quite malleable, and thus prone to stretching and deformation which could lead to failure.

Why should the clearance between power and telephone cables not be less than 300mm?
Telephone signal is more prone to EMI (Electro Magnetic Interference) effects of Electrical energy flowing through the power cable. To avoid such EMI effects, telephone cable is laid little bit away (300 mm at least) from the power cable.
Can a telephone cable be used for video?
no
What should be the distance between underground power cable and telephone cable?
300mm
Loose Clutch Cable?
get it tightened
Why would the emergency brake on a manual car not work?
The cable underneath probably came loose. Have it checked out.
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.
What is the best way to run an external coax cable?
Our family lives far off the road, so having comcast run the cable would be exorbitantly expensive. Could we hang the cable from telephone poles, or would that cause signal loss?
Is a cable company usually a DSL Internet Provider, too?
No. Cable internet is sent over cable lines, while DSL is sent over telephone lines. I know of no company that is both a cable company and a telephone company.
