I'll take that as "How are telephone wires connected?" but it's still unclear what you want to know. Telephone wires are connected just as any other wires are connected. By screw connections, by soldering, by crimping.
When they get colder, they will get shorter - and the tension will increase. That might make them break.
Copper is used for telephone wires because it is the second best conductor of electricity after silver (which is a little pricey).
