走铜线,跟天气气候没有关系。

Can weather affect my DSL connection?
Answer: Yes, it can. The primary cause of poor connections due to weather are moisture related. Since ADSL technology is electrical in nature, all of the exposed equipment can be affected by moisture which is an excellent conductor of electrical current. This, combined with the fact that the properties of water allow for "seepage", gives greater exposure to equipment that would, otherwise, be impervious to other weather conditions.
或者你可以问下学电子的同学,空气温度跟湿度都会影响铜线的阻力的,特别是接口没有保护层的地方很容易受影响。 |
