Factory Direct Sales NDGL Series 4 Pole 100A up to 1600A Load Isolation Switch Load Disconnect Switch
NDGL series load isolation switch(hereinafter called switch for short) is manufactured by our company with the up-to-date technique imported from europe. This product meets the international technial level in the late 1990S. Being the most ideal renewal of domestic congeneric products. This kind of lode isolation switch is widely used in the distribution system and automatic system of architecture, electrical power, petrochemical, and other industries. This kind of lode isolation switch possesses flexible structure of modularized design, possesses fiexible and versatile compositionality, it adopts the shell made by unsaturated polyester resin reinforced by glassfibre. It has very high dielectric performance. Protective capability, and reliable operation. The operating mechanism is an elastic energy accumulation accelerating mechanism for instant release, which makes instant on and off of the double breakpoint contact, It has no relationship With the speed of operating handle and increases greatly various electric properties. Many forms of structres and operations in which the on and off state of contact is observed through windows. There are operations inside and outside the board. There are frontal and lateral operations. There are connections behind the board. This kind of swich has a good-looking outline and various functions, being very novel, simple and small-dimensioned, and the best choice among the congeneric prouducts. Characteristics 1The elastic-accumulating accelerating mechanism for instant realizes the rapid making and breaking (13.8m/s), having no relationship with the speed of the operating handle, and increasing greatly the capability of extinguishing electric arc. 2The shell made of unsaturated polyester resin reinforced by glass fiber possesses excellent performance of flame resistant, dielectric performance and safe operation, resist carbonic performance and resist impact performance. 3Parallel double gap contact possesses self-cleaning functions. 4All the contact materials are copper alloy plated with silver, with two separation contact surfaces. 5Large distance of insulation 6Be on "0" position, the switch handle can be locked with three locks at the same time and thus avoid error operation. Product usage NDGL series load isolation switch mainly suitable for AC 50HZ, rated voltage to 600V, DC rated voltage up to 440V, rated current up to 3150A, The switch is used in infrequent making and breaking circuit. International Standard 1International standard IEC60947-1(1998) Low-voltage switchgear and control gear part one, general Rules 2IEC60947-3(1999)Low-voltage switchgear and control gear, switches disconnections, switch-disconneetors and fuse-combination units 3National standard: 4 GB/T 14084.1-2000 Low-Voltage switchgear and control gear, part one, general Rules 5 GB 14048.3 -2002 Low-voltage switchgear and control gear, switches, disconnections, switches-disconneetors and fuse combination units NDGL Series load isolation switch can work reliably under the following condition 1Height about level does not exceed 2000m 2Ambient temperature is ntot higher than 40Cand not lower than -5C; Relative humidity is not larger than 95% 3No explosive dangerous medium environment; 4No rain and snow attack environment; Note: If the load isolation switch is expected to be used in the condition that the ambient temperature is higher than +40C or is lower than -5C-45C, customers should inform to the manufactory.
