XTRA Guard 3 Alpha Electronic Shielded Cable

Alpha Wire engineered and manufactures an XTRA Guard 3 material that’s suitable for direct burial in the Earth without the costly use of conduit. These electronic underground cables come in unshielded, shielded, 300 volt, 600 volt and Alpha supra shield options.

XTRA guard 3 direct burial cables have 5 times the water resistance of standard PVC cables due to its specially formulated Ethylene Propylene Copolymer jacket. This gives the cable outstanding service life and ultraviolet light stability. It’s available is multiconductor and multi pair with as many as 60 conductors per cable.

Common applications for XTRA Guard 3 are inter-building communications, satellite communications equipment, land irrigation systems, outdoor security systems, outdoor scoreboards and displays and pipeline sensor controls. Alpha manufactures a superior cable for standard applications extending the life of the application to avoid replacement cables and installations in the future.

XTRA Guard cables also come in PVC jackets for high technology applications and TPE (Thermoplastic Elastomer) for mining, paper, wood and pulp operations. The TPE jacket has excellent low and high heat resistance from -60°C to 125°C. There’s a total of 6 types of XTRA Guard material covering most applications with a superior Alpha Wire type of electronic cable.

The standard foil shield that Alpha manufactures is an aluminum polyester foils shield facing in with a tinned copper drain wire. Common reasons for a foil shield are low cost, ease of termination, low frequency interface and 100% coverage over the core of the cable. They also make a supra shield which is an aluminum polyester aluminum foil shield with an overall braid shield for the maximum protection. Common reasons for a supra shield are high frequency interface and high physical strength.
