Based on years of experience in the metallurgical industry, we have developed a tunnel wire rod surface treatment production line of fully automatic & enclosed type. Itu2019s maximum production capacity can reach 400,000 tons/year. Its excellent performance and reasonable price has attracted wire rope customers from China and southeast Asia.

Switchgear describes a total collection of power circulation tools set up from key equipment as well as additional equipment according to a certain circuit strategy. It is utilized to control as well as secure circuits and also devices. The structure of the switchgear is roughly similar, mostly split right into busbar space, breaker room, secondary control area (tool space), feeder area, each area is generally separated by steel plates. low-voltage withdrawable switchgear 1. Understanding of distribution box (cabinet). GCK, GCS, MNS are low-voltage withdrawable switchgear; GGD, GDH, PGL are low-voltage fixed switchgear; XZW is a thorough distribution box; ZBW is a box-type substation; XL, GXL are low-voltage power distribution closets and also building and construction website boxes; JXF is an electrical control box; PZ20 and also PZ30 series are incurable lighting circulation boxes; PZ40 and also XDD( R) are electrical meter dimension boxes. 2. The impact of low-voltage power distribution closets. ( 1) It is practical to configure the power supply fairly. ( 2) When the line falls short, it is useful to regulate the range of the fault and also it is practical to promptly find the fault factor and remove it in time. ( 3) It is convenient to arrange circuit maintenance in pieces, without large power failure. ( 4) Various security gadgets such as fuses to prevent brief circuits and also air switches to stop overload can be easily positioned in the power circulation cabinet. 3. The make-up of the low-voltage power distribution cabinet. ( 1) The power distribution closet primarily includes: electrical wiring terminals, various buttons, defense tools (air switches, merges, and so on), measuring tools (voltmeter, ammeter, cycle meter, and so on), gauging tools (active and also responsive power) table). ( 2) There are many sorts of low-voltage power distribution closets, and also the components are very various. Taking the power cabinet as an example, from top to bottom: blade switch, current transformer, air button, as well as branch breaker. If you straight manage the electrical tons, there are contactors, thermal relays, as well as branch current transformers under the branch breaker. Obviously, there are ammeters, voltmeters, voltage conversion switches, and also indication lights. TControl power distribution closet. 4. The web content of each digit of the power distribution closet version. GGD low-voltage power distribution cabinet: G-- low-voltage power circulation cupboard; G-- set setup as well as wiring; D-- power cabinet;. GCK low-voltage power distribution cabinet: G-- cabinet structure; C-- withdrawable type; K-- nerve center;. GCS low-voltage power circulation closet: G-- enclosed switch cupboard; C-- withdrawable type; S-- Senyuan electric system;.
MNS low-voltage power distribution cabinet is an item made according to the transfer technology of Swiss ABB business. 5. The difference between GGD, GCS, GCK, MNS power circulation cupboard. GGD is different from the other 3 because it is a set type, while GCK, GCS, as well as MNS are all cabinet type button closets. Each electrical outlet unit of them is independent and also each circuit will certainly not impact each various other. GCS is a new generation of drawer type switch cupboard created by Senyuan Company in the mid-90s with reference to ABB's MNS cabinet kind. The main framework is similar to MNS, metal pretreatment line with the primary bus bar behind. The difference from MNS is that the cabinet module makes use of a 20mm module (MNS is 25mm); the cabinet adopts a press mechanism, which makes the procedure easier as well as flexible. The MNS cabinet can be operated on both sides, as well as a single closet can hold 36 loopholes (with 1/4 drawers) at the majority of, while the GCS can be approximately 22. The product made use of in the MNS cupboard is aluminum-zinc layered, totally set up structure, no post-processing (galvanizing) is called for. The straight busbars of MNS and also GCS are divided from the front left drawer device and the front right cable television outlet area with dividers. Their vertical busbars are put together in flame-retardant plastic practical boards to be much more trusted. The distinction is that GCS can only have 1/2 cabinet at the very least, MNS has 1/4 drawer, MNS drawer has an additional interlocking mechanism, as well as GCS just has the button itself.
