Weatherproof Line HMW-PE / Copper Cable Solid/Stranded Soft Medium Hard and Hard Drawn
Copper wire has been used and continues to be used in electric and electronic compounds because it can flow electricity quite easily and is a great conductor of electricity. Copper wire is a kind of metal with a number of contents present in it. Apart from its great conductive properties copper also has excellent tensile strength, ductility, solder- ability, easy to install, has great creep resistance, corrosion resistance and thermal conductivity. Copper wire comes in solid and stranded types.
At Nassau Electrical Supply, we are well versed with all there is to know about copper building wire. We provide all sorts of wire and cables that will provide solutions to all your electrical problems. Every single cable and wire has been uniquely engineered for particular applications and surroundings. Among them is the service wire weather proof line HMW-PE/ copper cable solid/ stranded soft medium hard and hard drawn. The conductor covered with black high molecular weight polyethylene is often used in overhead distribution systems in the event where protection from elements from the environment is needed.
Compliance to ASTM
The Weather Proof Line HMW-PE complies with the standards that have been set by ASTM (American Society for Testing and Materials). The conductor is classified as Strand Class A and Class AA (#1 AWG – 4/0 AWG). Normally class AA is normally used with bare conductors often used in overhead lines. On the other hand class A is for conductors that need to be covered with weather – proof materials, slow burning and for conductors that need greater flexibility than that provided by class AA.
The copper cable is concentric lay stranded (B- 8) which is to say that the cable is built using a central core wire and is surrounded by either one or many layers of laid copper wires where by each layer alternating in unilay, direction or uni-directional.It is also a B-1 conductor and thus a hard drawn conductor applied in overhead electrical distribution networks. Hard drawn copper can be difficult to work with in its original state. The stranding and bunching of the wires in the hard drawn state can be very difficult as well. However, through heat treating the wire at the right temperatures, the ductility of the copper can be restored making the wire soft and flexible once again.
The process of heat treating is referred to as annealing while the resulting metal that has gone through the process is called soft annealed copper metal. Temperature and time control the degree of annealing. Depending on how and where it is going to be used, copper is can be used with various degrees of annealing. As compared to soft annealed copper wire, hard drawn copper posses great tensile strength. Hard drawn copperwire has a tensile strength of 500 to 700 kilopound per square inch (ksi) and a conductivity of 97% IACS.
The Service Wire Weather- proof Line HMW-PE also meets ANSI C8.35/ICEA S-70-547the requirement set by the ASTM. Although this material covering is not regarded as an insulation material, it provides higher levels of protection from too much wind, tree limbs or any other elements that may interfere with the high voltage lead.
The cable is also sunlight resistant and is RoHS compliant. This is to say that it restricts the utilization of particular dangerous materials present in electric and electronic items.
