1. Superior Electrical Performance
Cross-linked polyethylene, as the insulating medium for cables, possesses exceptional electrical properties. Theoretically, its performance indicators are even better than those of oil-filled cables.
2. Excellent Heat Resistance and Mechanical Properties
The cross-linking process used to treat polyethylene resin significantly enhances its heat resistance and mechanical properties. Due to its excellent heat resistance, its normal operating temperature reaches 90°C, higher than that of oil-filled cables. Consequently, for the same conductor cross-section, its current carrying capacity is higher.
3. Easy Installation and Installation
Because cross-linked cables have a dry insulation structure, they do not require oil supply equipment. This greatly facilitates line laying and construction. Connectors and terminals are easy to install. Some connectors and terminals utilize prefabricated accessories, eliminating the need for oil handling, shortening installation time and minimizing the risk of fire on the construction site. Furthermore, line height differences are not restricted. They are suitable for installation in locations subject to vibration, such as on bridges, and eliminate the risk of oil mixing with the gas when connecting to GIS.
