Allowable Ampacity for 1 AWG 3C Stranded Aluminium Shield Overall BC Tape Red PE ARG7H1EX 18/30KV Medium Voltage Cable: 100 Amps

About:

This description pertains to a medium voltage cable that is rated for 18/30 kV (kilovolts) applications, indicating its suitability for higher voltage requirements compared to standard commercial or residential cables. The "1 AWG 3C" refers to a three-conductor cable where each conductor is 1 American Wire Gauge (AWG) in size, denoting thick conductors that can handle larger current loads.

Also Known As:

Such a cable may be known by different names, reflecting its construction and application, such as "18/30 kV aluminum stranded medium voltage cable," "1 AWG triple-core aluminum shielded cable," or "medium voltage power cable with red PE insulation." These alternate names can vary but generally convey the cable's primary characteristics and applications.

Application:

It is designed for significant electrical installations where medium to high voltage power transmission is required. Typical applications include power distribution networks, connecting substations to industrial, commercial, or residential complexes, and providing power in environments where durability and reliability are critical, such as underground, outdoor, or industrial settings.

Standards:

The cable should comply with international and national standards applicable to medium voltage power cables, ensuring its reliability, safety, and performance. This might include compliance with IEC 60502-2 for medium voltage cables or similar standards, dictating requirements for construction, performance, and testing.
