10 Points on PILC Cables

10 Points on PILC Cables Definition: PILC cables are Paper-Insulated Lead-Covered cables used for medium-voltage underground power distribution. Insulation: The primary insulation in PILC cables is paper, which provides good electrical insulation properties. Sheathing: The paper insulation is covered by a lead sheath, which provides mechanical protection, moisture resistance, and helps to prevent corrosion. Application: PILC cables are commonly used in underground power distribution systems. Installation: In the United States, most PILC cables were installed in conduit or duct systems, rather than being directly buried in the ground. Historical Use: PILC cables have been used in the United States since the late 1800s, making them a long-standing technology in the power industry. Medium Voltage: PILC cables are designed for medium-voltage applications, typically ranging from 4.16 kV to 34.5 kV. Advantages: PILC cables offer good electrical insulation, mechanical protection, and moisture resistance. Disadvantages: PILC cables can be heavy and bulky, making them more difficult to install compared to some modern cable types. Modern Alternatives: While PILC cables are still used in some applications, modern alternatives like Cross-Linked Polyethylene (XLPE) cables are becoming more common due to their lighter weight, higher temperature rating, and improved performance.
