450/750 V Stranded Copper Conductor PVC Insulated Thw Wire

60227 IEC 01 (THW)
450/750 V 70°C solid and stranded conductor PVC insulated, single core

THW Applications:
The copper conductors type THW are used for power and lighting circuits in industrial, commercial and residential facilities where it is required of more security, just as it is specified in the National Electrical Code. This type of conductor can be used in dry and wet places; its maximum temperature of operation is of 75 ºC and its voltage of service for all the applications it is 600 V.



THW Structure:

Conductor	Solid and Stranded annealed copper Size: 1.5 mm2 up to 400 mm2
Insulation	Polyviny chloride (PVC) Color: Black, Blue, Red, Brown, Gray, Green/Yellow, any colour
Classification	Maximum conductor temperature 70ºC Circuit voltage not exceeding 750 volt
Testing Voltage	2500 VAC
Reference Standard	IEC 60227
