Cable alarm for less Due to increased international demand countrys like China and India, prices of items commoditiy has skyrocketed in recent years. This cost increase is particularly evident in the markets for metal products. Because copper is the key to low-voltage electrical alarm and audio cables and metal is a commodity the cost of low voltage wire and cable have also grown substantially in recent years.
Another factor contributing to the cost of low voltage wire and cable is how much processing of copper production is involved in making a particular type of copper conductor wire for low voltage and is much more cable.There treatment and therefore cost in the manufacture of stranded copper conductors. A cheaper alternative is to use solid copper conductor wire and cable, because it requires no additional processing costs for the production of copper wire and cable strand conductors.Wire based solid bare copper conductors is not as flexible as those made with stranded copper conductors. The loss of flexibility is established for the lower cost of solid conductor wire and cable. Most alarm systems use a low voltage small size (22 AWG). Wire size and small loss of flexiblity cable does not justify the cost savings from the use of solid conductor wire.
In today's market, the cost of a two conductor 22 gauge (awg.) stranded bare copper cable signal would be about $ 29.50 (U.S. Dollars) per 1000 feet (304.8m) of wire. The cost of a two conductor 22 gauge (awg.) solid bare copper wire alarm is $ 26.95 (U.S. dollars) by 1000 feet (304.8m) of wire. Using the solid bare copper wire alarm chef would save 8.64%.
Here's another example: This driver 2 22 indicators solid bare copper wire alarm costs only $ 20.75 (U.S. Dollars) per 1000 feet (304.8m) of wire. If the driver 2 strands bare copper wire security costs $ 29.50 (U.S. dollars) by 1000 feet (304.8m) of wire, you save $ 8.75 (U.S. dollars) by 1000 feet (304.8m) of wire or of 29.66%.
Here is a more detailed description of the alarm cable which costs only $ 20.75 (U.S. Dollars) per 1000feet (304.8m) of wire:
Unshielded Cable: 22 / 2 solid bare copper WRC 1000 feet (304.8m) rolls Brown * Weight per 1000 feet (304.8m) spool of 10 lb (4.5 kg) * The amount of the correct order is total of 1000 feet (304.8m) rolls needed. If 5000 ft (1524m) is necessary so that the amount is 5 order. (5 reels of 1000 feet Applications 304.8m *): Nurse Call, Home alarm system, zone fire alarm, home security, home entertainment, communication cable, control cable, home automation, Sound System, Intercom System, sound, security system, control circuits of limited power, commercial security approvals *: NEC Article 725 Type CMR & 800 & MPR CL3R, Type FT-4 CSA, UL Subject 13 and 444, Fire Marshal of the State of California, 75Degree -20 C, 300 volt insulated conductors rated College *: * PVC Jacket: PVC Riser rated cable opening Ascending Descending Markers & Video * 4 x 1000m reels in a box * increments 4. Example 4 coils, 8 or 12 coils coils etc..
Use solid bare copper conductor wire and cable and save your money!
