Electrical supply cables made of copper wire are known to be strong because they don’t wear out easily. When we talk about the type MC Copper Conductor Cable we refer to a conductor wrapped with polypropylene and THHN or THWN insulation. Nassau National Cable is one renowned site that produces some of the best qualities of this product. Not only great stuff on Type MC but also top notch versions of a variety of  Wire and Cable Products. Their electrical and electronics cable products are made of superior materials that meet the standards of the UL. The cables also have resilience features that enhance their performance regardless of the environment it is buried or suspended overhead.

On this post I’ll share with you about the Type MC Copper Conductor and why you should consider it in serving your power supply connection.

Safety First!
You will agree with me that electric currents are very dangerous when distributed in a careless manner and may cause death if not transmitted using high quality cables with appropriate safety attributes. Nevertheless, many manufacturers and contractors out there like shortcuts and would resolve to manufacturing or acquiring cheap and low quality cables to serve your power needs, this would put your life and the life of your loved ones at risk, a fact that’s so unfortunate. Always ensure that your wiring is done using quality products and remember that cheap is expensive because when you use cheap wires, they’ll wear out in no time and you’ll have to replace them over and over; this is expensive in the long run.

Construction of the Type MC Copper Conductor
Type MC copper cable is comprises of a stranded copper conductor insulated with a thermoplastic THHN insulation, which is a known to be a high heat resistance nylon coatto affirm steady conductivity all through the life of the cable. The core also has a grounding wire to help with discharging of charges which would otherwise accumulate to pose danger, the grounding wire is often coated in green for easy identification.

The assembly of conductors is then wrapped together ina binding cable tape, to ensure that they sit firmly in place; after which it is coated with a strong interlocking aluminum strip armor which protects the cable from both mechanical and chemical damage.

It is advisable that whenever you get ready to purchase anything from the market especially the electric cables, you should ensure that it is tailored to meet your specifications of the current carrying capacity as well as the method of transmission to be deployed. Electric current can only be transmitted using two main methods; that is the Underground Power Transmission in which cables are buried underground and the Overhead Power Transmission method, where cables are suspended on electric poles, the Type MC Copper Cable works on either options

Testing, Approvals and Certifications
The ideal purpose of testing and certifications on all products is to ensure that they meet the relevant safety and quality specifications expected of them. After the construction, all Type MC copper conductor is then tested according to International standards of the UL (Underwriters Laboratories) to ensure that it meets all the required approvals.

Nassau National Cable offer type MC Cable that meet the following specification standards;

  • It transmits current of up to 600 volts in accordance with the UL
  • Type MC copper cable passes the Flame test of IEEE as well as FT-4, ICEA T – 29-520
  • NFPA 70 NEC Article 330; ARRA 2009 of Section 1605 

Why Go for Type MC Copper Conductor?
Each and every type of electrical currying conductor is designed with unique features to help boost its appropriate operation accordingly. This cables has resilient components that boosts its lifespan as well as enhancing its power supply.

The copper conductors are of Class B annealed concentrically drawn soft copper wires. Soft copper wire offers more flexibility.Who doesn’t need a flexible cable? An electrical transmitting cable should be flexible enough for easy shipment and installation. When a cable is flexible it requires less effort for twisting and bending as well as making it into drums for shipment.

The copper conductor is also insulated with THHN/THWN that is thermoplastic which apart from offering protection against high heat, also protects the conductor from corrosion as well as water/moisture. Electric cable should be kept dry and free of moisture all the time and this explains the use of THWN.

There are harmful and reactive chemicals that when in contact with the soft copper conductors would corrode them, which in turn leads to electric faults and even blow outs. This is not good because some of this cables may be used in hospitals to run heavy lifesaving machines and you can imagine what may happen to a patient whose life is being monitored using this machine in case of sudden shutdown.

Grounding wire for safety
The cables also has a grounding wire which is of Class B copper wire. The main aim of this grounding wire is to ensure steady electric current conductivity via the phase electrodes for the entire life of the cable. It is insulated to provide further protection against mechanical and chemical destruction. Mechanical damage refers to damages caused by any external force applied on the cable during installation or packaging, while chemical damage refers to damages as a result of hazardous chlorides, alkali, acids etc. that would react and corrode the copper grounding wire.

Type MC copper conductor is insulated with cross linked (XLPE) polyethylene insulation. Is it safe to handle uninsulated electric conductor? Of course not, definitely you’ll get electrocuted. For this reason, the copper conductor type MC Cable is insulated for you to prevent putting your life at risk and you can be rest assured of your safety even as you carry out your installation. Cable insulation is very important because a part from keeping the electricians from unnecessary electrocution, it also keeps the cable from strong direct sunlight rays, overheating as well as corrosion.

Strong UV rays is capable of causing wear and tear to your cable if it lacks proper insulation like the type MC copper cable. Electric current flowing in the conductors at times would cause overheating which also causes wear and tear and in turn lead to power blows, this is prevented by insulation.

Fillers and binder tapes are used to ensure that the soft copper conductors and the grounding wires are assembled together, by filling the unused spaces to form a complete cable. It is also jacketed with a polyvinyl chloride (PVC) that is known to be non-biodegradable due to its plastic in nature. This improves the life of type MC copper cable especially when buried underground. PVC makes it more durable since it does not decompose at all, thus maintaining cable life.

Versatile Temperature Range
You don’t need to worry about changes in the environmental conditions when serving power using the type MC copper cable. It has a temperature rating of as low as -40 degrees, which so it can efficiently operate in wet areas experiencing such temperatures. The wide range of operational temperatures means that this cable can be laid in either wet or dry environmental temperatures, because of its versatile in temperature range.

Type MC copper conductor cable is armored with strong interlocking aluminum strip which encases the assembly of jacketed copper conductors as well as the grounding wire. Interlocking strip protects the cable from flames in case of fire outbreak. Fire outbreak is an uncertainty that may occur at any time and can be very destructive when it occurs, this calls for special measures like the use of interlocking aluminum strip which a part from offering protection against flames also keep the cable from corrosive chemicals and mechanical damages by people and objects. No doubt electric cables need this strong interlocking aluminum strip for protection.

The type MC copper cable is pocket friendly especially when installed in conduit systems, this is because you don’t need to incur further costs in purchasing other interlocking cable strips. It is therefore a great economic alternative to contractors installing power cables in conduit systems.

Where does Type MC Copper Conductor Applied?
Different cables sold by Nassau National Cable are intended to serve in different areas. There are cables that can only be used indoors while others are used in outdoor power connections. Some cables are also dual purpose and can as well be deployed in both indoors and outdoors connections. Contractors may also order for cables based on the method of power distribution he or she intends to use, can either be overhead power transmission or underground transmission.

Most common use of this cable is in processing mills where it is used to supply power that for running large machines, and also controls the circuits in the mills.
