CURLEW - NEW AND USED MARQUEES

If you are building your own extention leads this may be usfull. 

Many extention leads are made out of Arctic cable (it's remains flexible at low tempretures.) Normaly in a blue colour (yellow is used for 115v) 

However most are now using HO7 cable. 

Arctic cable is, as it's name suggests, suitable for use in sub zero temperatures, that is it, nothing more.

In comparison to standard flexible cable arctic cable is more flexible and has a slightly thicker insulation and sheath. There is no particular reason to expect it to be any better than normal flex beyond that. Compared to arctic H07RNF has even thicker insulation / sheath, is resistant to more materials, is still pretty flexible, can be used in sub zero temperatures, has a higher voltage rating and is designed for the environment.
