Power Fitting DB Type Adjusting Plate Ploe accessories
Power fitting DB type adjusting plate is one steel plate with many holes but different hole distance; it is applicable to insulation fitting for adjusting the length of twin-connecting or parallel-connecting insulator string through series connection with insulator string. It is also serially connected with the section of bundled conductor between connecting fitting & tension clamp subjected to tension insulator string as the looseness adjustment of two pieces of bundled conductor.
