Electrical transparent terminal block

      DJ6/DFY1,2 type energy measuring terminal blocks are special terminal blocks applied for standard wiring in energy measuring equipment.They are also suitable for secondary circuit of rated voltage up to 660V and rated current up to 20A.They are used to change or inspect the electric equipments such as energy meter,electric instrument and relaying equipment under on-load circumstance.They can guarantee operation safety and improve fieldwork efficiency.

      In order to satisfy customers' demand,our company improves the design and adopts America-imported high-molecular polycarbonate material. It has advantages of high impact resistance,ageing resistance,anti water-absorption,flame retardant,high temperature resistance.It not only has bright and elegant appearance,but also excellent product performance.It solves former products problems such as fragile,easy mildew stain grow,or heavy CT secondary leakage,easy PT secondary breakdown,etc..This kind of terminal block is an ideal successor of the older generation.
