Continuously corrugated welded (CCW) armored type cables, UL designated as Type MC-HL are being specified and used in all types of oil and gas, industrial, commercial, utility, installations to supply electrical power to motors, pumps, fans, and other equipment. A large percentage of these cables are extensively used in the petrochemical industry. Its use has become so wide spread that the National Electrical Code (NEC) has permitted its use in a variety of code articles. This paper will review the various advantages and uses, code articles, and the proper methods used when installing CCW armored cable. ©2010 IEEE.

An analytical approach is presented for estimating the total resistive loss in the randomly positioned conductors of a multiple circuit, three-phase cable system, as in a duct bank. By breaking the total resistive loss into three components, i.e., skin effect loss and two independent proximity effect losses, the problem is simplified so that each loss component can be computed separately. A semi-empirical formula for determining the proximity effect loss from a single external source current is established, which is the building block for solving the total proximity effect loss. For a typical three-phase duct bank scenario, the proposed approach achieves good agreement in predicting the total resistive loss when compared to finite-element analysis simulations. © 2011 IEEE.
