Cutting Machine is a machine that shears a sheet by reciprocating linear motion with one blade relative to the other. By means of the moving upper blade and the fixed lower blade, a reasonable blade gap is applied to apply shearing force to the metal sheets of various thicknesses, so that the plates are broken and separated according to the required size.

[ China Instrument Network Instrument R&D ] Recently, Long Cable Electric Technology Co., Ltd. announced that it has received the "New Product Appraisal Certificate" issued by the China Electricity Council, the company's 290/500kV XLPE insulated power cable accessories and ± Two new products of 525kV (±535kV) XLPE insulated DC cable accessories have passed the identification of new products and new technologies of China Electricity Council, which has filled the domestic gap and reached the international advanced level.
Founded in 1958, Long Cable Electrical Technology Co., Ltd. specializes in the design, manufacture and construction of cable accessories. The company witnessed and participated in China's 60 years of economic construction and rapid development. With advanced technology, high-quality products and reliable services, the company successfully completed the national major energy engineering, power transmission engineering and rail transit engineering participation tasks.
With the development of many ultra-high voltage, long-distance and heavy-duty transmission projects in China, the demand for high-voltage cable transmission is increasing, but there is no corresponding domestic cable accessory to match it. Currently, the domestic ultra-high-voltage cable transmission line is used. Cable accessories are also mainly imported from abroad. In many project bidding, foreign cable companies use their accessory technology to restrict domestic cable manufacturers from participating in competition. This has seriously affected the promotion and application of domestic ultra-high voltage cables. Ultra-high voltage cable accessories have become the bottleneck in the development of the cable industry.
To this end, Chang Cable Electric Technology Co., Ltd. has stepped up research and development, and successfully developed two new products: 290/500kV XLPE insulated power cable accessories and ±525kV (±535kV) XLPE insulated DC cable accessories.
The 290/500kV XLPE insulated power cable accessory products have passed the type test and pre-qualification test verification, and all technical indicators meet the requirements of relevant standards such as IEC 62067. The appraisal committee unanimously agreed that the 500kV cable accessory products have reached the international advanced level and agreed to pass the product appraisal, which can be mass-produced.
The ±525kV (±535kV) XLPE insulated DC cable accessory products have passed the type test verification, and all technical indicators meet the requirements of GB/T 31489.1 and other related standards. The appraisal committee unanimously agreed that the 525kV (535kV) DC cable accessory product technology filled the domestic gap and reached the international advanced level, and agreed to pass the technical appraisal.
The acquisition of this appraisal not only has a positive impact on the future market development and technological development of Changju Electric Technology Co., Ltd., but also helps to enhance the company's core competitiveness and profitability. It also marks the technical bottleneck restricting the development of domestic cable systems. Finally, it will be broken and will reconstruct the market competition.
