Electrical Properties Physical Dimensions Environmental Resistance Mechanical Strength Temperature Handling Conditions The proper cable size is governed by the amperage, voltage drop, and space available between the tubing collar and casing. A range of conductor sizes are available to meet application. requirements. Cables are available in either flat or round configurations.                               FLAT				ROUND Cables can be installed in wells where bottom hole  temperature is excess of 300 degrees Fahrenheit.
