Product Detail
The XP-70 U70BL Porcelain 70kN Disc Insulator is designed for overhead power transmission and distribution systems requiring balanced mechanical strength and reliable insulation performance.
Compared with higher load models such as the U120B 120kN porcelain disc insulator, XP-70 provides a practical solution for general overhead line applications.
With 70kN mechanical strength, XP-70 U70BL meets common overhead line requirements while maintaining installation flexibility.
Electrical porcelain construction ensures:
High insulation capability
Weather resistance
Long service life
XP-70 U70BL porcelain insulators are suitable for:
Distribution networks
Medium voltage transmission systems
