Service Wire 400 Hz USE-2 RHH or RHW-2 600 Volt Copper Cable Service Wire Cheap Sale

Service Wire 400 Hz USE-2 RHH or RHW-2 600 Volt Copper Cable

USE-2 stands for Underground Service Entrance and -2 indicates ninety degrees temperature rating. RHH refers to Rubber insulation High Heat resistant whereas RHW represents Rubber Heat and Water resistance. Therefore, the only difference between RHH and RHW cable is that RHH cable lacks the water resistivity feature even though they all carry up to 600 power volts and applied in similar lighting. For a cable to be branded as an underground service entrance, it should possess adaptive features that can withstand the underground pressure among others. 

This type of service wire is made of bare stranded, soft drawn copper conductors meeting the standards of ASTM B3 and B8. These conductors are insulated with a cross linked polyethylene (XLPE), which is adaptive to adverse environmental conditions. It comes as a six twisted conductors around one neutral wire and ready for use with a frequency rating of 40Hz.

Ratings and Approvals
It is necessary for electrical cables to be tested and approved before letting it reach the public hands. However, some companies get away with it and offer low quality cable products which have not been tested and approved as per the required international Underwriters Laboratory standards. As for this service wire, it conforms to the following specifications:

1.ASTM B3 and B8
2.UL 44 ICEA S-95-658 or NEMA WC-70
3.RoHS Compliant
4.Sunlight resistant

Why go for this cable?
Copper is well known for its tensile strength and great electrical conductivity which conventionally affirms why it is primarily used as conductors. Soft copper wires are flexible and easily succumb to folding and bending. Electrical cable installation is a procedural process that may get tiresome and hectic especially when handling rigid cables. Rigid cables are tough and will require more force to bend and fix as compared soft flexible copper conductors. Flexibility is an aspect to consider when it comes to electrical cables.

Bare copper conductors are insulated with XLPE compound that plays two roles; it protects the life of the person handling the electrical cable as well as protecting the cable from external and internal damages. You are likely to get electrocuted when you get into contact with a bare cable, but your safety is well taken care of by XLPE insulation. External damages refer to harsh environmental conditions such as corrosive chemicals and mechanical impacts, while internal protection offered by XLPE ensures that the live copper conductors do not get into contact with the neutral wire, hence improving electrical conductivity.

Applications
As pointed out earlier that different cables are designed for different purposes, this service wire is meant for use as a communication cable. It is applied for installations in TV and radio stations, mainframe computers, airport terminals, aircraft ground wire etc. When you make wrong cable choice and install it in your wiring systems, believe you me that it will be very costly to you.
