RWU-90 Cable can be used for impressed current and galvanic cathodic protection. Being a cable that is rated for direct burial, it is commonly used with sacrificial Magnesium and Zinc anodes. For impressed current applications, RWU-90 is commonly used for continuity bonding and for semi-deep anode install applications. For extended lead lengths for Coupons and permanently installed reference electrodes, RWU-90 is also the cable used for this application due to the operating temperature range of the cable.
