Metal Clad and Interlocked Armor Cable

Metal Clad (MC) refers to a metallic coat that offers protection against chemical and mechanical damage. Whereby, chemical damage may be as a result of corrosive chemicals getting into contact with live wires causing a reaction that in turn corrodes the power wires. Mechanical damage is mainly caused by external force e.g. crashing that may occur during shipment and installation of the cable. It is true that some power cables are made of metallic cladding material to boost their performance, so what’s different about the performance of these Metal Clad cables? MC cable has an insulated grounding wire that when terminated on both ends, can make a reliable return route for fault current to flow thus facilitating overcurrent device to do its defensive role. Some power cables achieve their protective mechanism due to the presence of an Interlocked Armor. Interlocking armor is almost the same as the MC. However, an armored cable has its metallic sheath in contact with the grounding wire that can as well serve as an equipment grounding wire. The interlocking armor is often made of aluminum strip or copper. Cables instilled with an interlocking armor relieves the users from extra costs incurred if the cable was to be deployed in conduit systems. This is because you don’t need to spend much on buying other interlocking strips. CCW MC-HL refers to Continuously Corrugated Welded cable to play the same role of both MC and interlocked armor. These cables are designed and manufactured to withstand harsh environmental conditions. For contractors looking for durable cables, go for types MC, Interlocked Armored and CCW cables because a part from their protective mechanisms they are as well economic alternative. Serve your power line with strong durable cable that will relieve you from continuous unnecessary cable inspection costs. Why go for type MC, armored and CCW-HL Cable?  You will agree with me that power that offer self-support especially when installed vertically is the cable that you need for your power line. This is because you don’t need to spend much time cross-checking in between the cable trays to confirm the connection system. This cables are such easy to install. Who doesn’t need a cost effective cable? Because of the interlocked Armored Aluminum strip CCW and type MC cables are cost effective alternative to installation in conduit systems, cable trays etc. since you don’t need to incur cost in buying other traditional interlocking metal strips. These cables are lightweight and flexible due to the interlocked aluminum strip. Lightweight cables are easy to handle and require less effort to carry during installation and also less effort to wound into drums for shipment because of their flexibility. Insulation of these cables are much superior because they are made of lead free and flame retardant Polyvinyl Chloride (PVC) and the temperature retardant Cross Linked Polyethylene insulation material. Applications Cables with such features are widely used in outdoor and indoor installations. They can as well be buried in conduit pipes, cable trays, or even used in aerials. Can also be used in wet and dry environmental conditions. They are tested and approved to meet the standards of Underwriters Laboratory (UL) specifications which include; 1.Flame Test compliances e.g. IEEE 383 2.Industrial Compliances e.g. ICEA S-96-659/NEMA WC71, UL Type MC, UL File.
