CMR Multi-Conductor Electronic Wire (Shielded)
Multi-conductor Non-Plenum Shielded
Multi-conductor non-plenum cable is a good quality electronic wire preferred for use in many circuits due to its standard qualities and its availability at pocket friendly prices to the customers. The cable has good chemical and physical properties that not only make it good for cabling but also gives it a long lifespan hence no need to frequently replace the cables. The Multi-conductor non-plenum Shielded cable is made of a fully annealed stranded copper wire. Copper has excellent conduction properties thus annealing and stranding only adds to its already excellent properties. The copper conductor is then insulated with polypropylene insulator.
The multiple insulated conductors are then covered with an external jacket made of Polyvinyl chloride (PVC). PVC is among the best insulation and jacketing materials due to its toughness and good resistance to factors that would otherwise poison the conductor. The cable is then fitted with an aluminum foil shield with a grounding wire that helps to cub the electromagnetic effect. These good properties of our Multi-conductor Non-plenum shielded cable gives it a wide range of applications and in different environments of work. The cable meets the international approval standards and therefore is certified for use as listed by the manufacturer.

Copper is the main conductor of the Multi-conductor non-plenum cable. The 22- 12 AWG copper wire is fully annealed and stranded per ASTM B-3. Annealing the copper involves a thorough heat treatment to alter its chemical and physical properties in order to lower its internal resistance so that the current flows through more easily hence making it a better electrical conductor. The copper is then stranded in rope-layby to make it more flexible and to reduce its resistance further, since stranding increases the surface area for conduction.
Copper on the other hand is the best metal in electrical conductivity. Its excellent conductivity is majorly contributed to by its atomic structure. The outermost energy band of copper is partially filled with electrons; this creates more space for more electrons to carry electrical currents for conduction. Besides its good electrical conduction, copper is also a good thermal conductor. Good thermal conduction aids in dissipating extra heat that is not needed in the system, this helps to protect the conductor, insulators and jacket from melting. Copper also has good creep, stretch, nick and break resistant. The creep resistance is its ability to resist loosening at joints hence insuring a firm connection.
The copper conductor of the Multi-conductor non-plenum cable is insulated with Polypropylene, PP insulator. The PP is a premium grade and multicolored. The insulators being many have to be colored differently for easy identification during installation to prevent wrong wiring. PP is a thermoplastic polymer made by joining short chain propylene. This insulator has good physical and chemical properties that resists most bases and dilute acids that often eat up the cables when they come into contact with them. It is also tough and vey elastic, making it a good fire retardant. In case of a fire, it just melts and change shape but does not get consumed thus preventing fire spread. Its flexibility is important especially when folding and bending is required during installation and transportation. PP is also resistant to fatigue and can retain its shape when the stretching force is removed.
The multiple cables of our Multi-conductor non-plenum cables are covered with an overall jacket made from Polyvinyl Chloride, PVC. PVC being a versatile thermoplastic can be modified with lubricants, stabilizers and plasticizers. It also has the excellent resistance to acids, oils and bases. PVC is tough, durable and is able to resist abrasion as well as being a good fire retardant. Its good weather resistance is useful in preventing the conductors and insulators from the effects of moisture, UV light and weather.
The multi-conductor non-plenum cable has a thin aluminum foil shield. The shield is put in place to become a good barrier against AC of low frequency by channeling the electrical fields to the ground via the grounding wire. The shield also prevents the system and circuit from effects of high electromagnetic effects that would interfere with its functioning. This type of shield is strong, flexible, durable and easy to install.
Multi-conductor non-plenum cable has multiple uses. As seen from its physical and chemical properties, it can function in many environments effectively.
