Cross Arm
11, 20 and 33 kV Cross Arms are as per the latest REC specifications and manufactured by Pultrusion process.
Features:
- Weather resistant specially suited for coastal areas
- Light weight for easy installation in hilly areas
- Avoidance of birdage problem
- Continuance of power supply even after insulators are cracked
- Lower size insulators can be used reducing the cost of insulators
