alarm security system: Solid Bare Copper Security Cable vs Stranded Bare Copper Alarm Cable

Countries like China and India have increased demand for raw materials like copper, that the cost of these commodities have increased dramatically in recent years. Because copper is a key component of the cable, the voltage signal will also increase the value of the factor significantly.Another for the cost of wires, cables, low voltage level of copper processing involved in producing a certain type of conductors copper for low voltage and processing more cable.There and, consequently, the cost of production of copper wire braided.



A less expensive alternative is to use a solid conductor copper wire and cable, since it requires no further elaboration of the production costs on a wire twisted copper cable conductors.Wire make solid bare copper conductors is so flexible that they are were made of stranded copper. Decreased, alarm security system, flexibility to do to reduce the cost of solid fuel bare copper wire for alarm. Most alarm systems use low voltage, small size (22 AWG). The size of the wire and a small loss of flexibility of the cables is not limited to justify the basis of savings in the use of solid conductor wire.



In market today, the cost of 2 conductor 22 gauge (AWG copper. Stranded wire will cost about safety $ 29.50 (USD) per 1000 feet (304.8m) of wire. Room 2 Conductor 22 Gauge (awg.) solid bare copper wire, the alarm is $ 26, 95 (dollars) to 1,000 meters (304.8 m) of wire. If you use solid copper wire alarm red save 8.64%. This is another example: this gauge 2-conductor 22, is strongly red copper wire, an alarm is only, alarm security system, $ 20.75 (USD) for every 1000 feet (304.8m) of wire. 2 If a protective safety earth wire copper costs $ 29.



50 (WAS dollars. UU.) for every 1000 feet (304.8m) of wire, you Save $ 8.75 (USD) per 1000 feet (304.8m) of wire, or 29.66%. This is a more detailed description of the concerns that cable is only $ 20.75 (USD) per 1000feet (304.8m) Cable: Shielded cable: 22 / 2 solid copper WRC 1000 feet (304.8m) reels Brown * weight of 1000 feet (304.8m) tail, alarm security system, is 10 pounds (4.5 kg) * in the correct amount is the total number of 1000 feet (304.8m) rolls needed. If 5000 feet (1524m) is required then the correct order quantity is 5.



(5 reels of 1000 m 304.8m) * Application: Nurse Call, the main alarm, fire alarm zone The residential security, home theater, communication cable, cable management system, Home Automation, Sound System, Intercom, Public Address System, Security System, Power Chain Management Limited, the commercial security * Validation: NEC Article 725 and 800, Type CMR, CL3R and Mongolia, type FT-4 CSA, UL Subject 13 and 444, California State Fire Marshal, -20 to 75Degree C, 300 volt rated insulation * Director: * PVC Jacket: Riser Rated PVC , rope climbing and markers Descending, alarm security system, * 4 x 1000 m reels Order * Safe in Section 4.



Example 4 rolls, rolls of 8 or 12 rolls firmly ect.Use bare wire copper wire and cable and save
