现应大量用户的要求，我公司完成了改进设计，并采用了美国进口的高分子聚碳酸酯新材料注制，具有抗冲击强度高、抗老化、不吸水、能阻燃、耐高温等诸多优点，色泽鲜艳，外形美观，产品性能进一步提高。从根本上解决了原胶木产品脆性易碎裂、吸水起霉点， 造成CT二次泄漏大，PT二次易击穿的缺点，盒内各回路中设有测试孔，极大地方便了检查和测试，该接线盒为更新换代产品。该接线盒为更新换代产品。
各项技术指标均符合国家标准要求。试用单位反映，采用该新产品后，有效地防止了电能的漏计，是电能计量工作者的好帮手。对杜绝电能计量事故的发生，起到了积极作用。 | XKM／DFY1, 2 type energy measuring terminal blocks are special terminal blocks applied for standard wiring in energy measuring equipments. 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.
The technical parameter of this product is in conformity with international standards. Feedback from users shows that new type of this terminal block is capable of preventing missing elect r ic energy measurement . It is helpful for energy measuring work, and can put an end to energy measuring a c c i d e n t e f f e c t i v e l y. | | 二、主要技术指标 Main technical parameter | 1、额定绝缘电压Rated insulation voltage：660V、50Hz/60Hz
