Product Description
This is a 15kV single-core URD underground distribution power cable with TR-XLP tree-retardant cross-linked polyethylene insulation of 133% thickened insulation grade, concentric neutral structure, complying with ICEA standards, designed for direct buried medium-voltage power transmission with excellent moisture resistance, anti-tree aging performance and large electrical safety margin.
Application
15kV URD cables are specifically engineered for primary underground distribution in medium-voltage networks. They are designed to withstand the rigors of direct burial or installation in duct systems, providing a reliable link between the utility substation and local transformers.
- Maximum conductor operating temperature under normal conditions: 90°C
- Emergency overload temperature: Not to exceed 130°C
- Short-circuit temperature (maximum duration: 5 seconds): Not to exceed 250°C
- Available manufacturing options: Water-blocking components integrated into the metallic section, designed for humid and wet service environments
Applicable Standard
ASTM B230, B-231, B-609
ANSI/ICEA S-94-649
AEIC CS8
Construction
Conductor: Class B aluminum or copper stranded conductor (compressed stranding).
Conductor Shield: Extruded semi-conductive compound
Insulation: Cross-linked polyethylene (XLPE) or tree-retardant cross-linked polyethylene (XLPE-TR)
