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 complete collection of power distribution tools put together from key equipment and additional devices according to a specific circuit plan. It is made use of to regulate as well as shield circuits and also tools. The structure of the switchgear is approximately similar, generally divided right into busbar area, breaker area, secondary control room (instrument space), feeder room, each area is usually divided by steel plates. low-voltage withdrawable switchgear 1. Recognizing of distribution box (closet). GCK, GCS, MNS are low-voltage withdrawable switchgear; GGD, GDH, PGL are low-voltage fixed switchgear; XZW is a thorough circulation box; ZBW is a box-type substation; XL, GXL are low-voltage power circulation cabinets and also construction site boxes; JXF is an electric control box; PZ20 and also PZ30 collection are terminal lighting distribution boxes; PZ40 as well as XDD( R) are electrical meter dimension boxes. 2. The impact of low-voltage power distribution cupboards. ( 1) It is convenient to set up the power supply reasonably. ( 2) When the line falls short, it is valuable to manage the extent of the fault and also it is hassle-free to quickly locate the mistake factor and also eliminate it in time. ( 3) It is practical to set up circuit inspection and repair in pieces, without massive power interruption. ( 4) Various defense tools such as merges to stop brief circuits as well as air buttons to stop overload can be conveniently placed in the power distribution cupboard. 3. The make-up of the low-voltage power circulation closet. ( 1) The power distribution closet mostly consists of: circuitry terminals, various switches, defense tools (air buttons, merges, etc.), measuring equipment (voltmeter, ammeter, cycle meter, etc.), measuring tools (energetic as pretreatment machine well as responsive power) table). ( 2) There are many types of low-voltage power distribution closets, and the elements are really various. Taking the power closet as an example, from leading to base: knife switch, current transformer, air switch, and branch circuit breakers. TControl power distribution closet. 4. The web content of each digit of the power circulation cupboard model. GGD low-voltage power distribution cabinet: G-- low-voltage power distribution cupboard; G-- fixed setup and circuitry; D-- power cupboard;. GCK low-voltage power circulation closet: G-- cabinet structure; C-- withdrawable kind; K-- nerve center;.

MNS low-voltage power distribution cupboard is a product produced based on the transfer modern technology of Swiss ABB company. 5. The distinction between GGD, GCS, GCK, MNS power distribution cupboard. GGD is various from the other 3 because it is a fixed type, while GCK, GCS, and MNS are all drawer kind button cabinets. Each outlet unit of them is independent and each circuit will not influence each other. GCS is a new generation of drawer type switch cupboard created by Senyuan Company in the mid-90s with recommendation to ABB's MNS closet kind. The main structure is similar to MNS, with the primary bus bar behind. The distinction from MNS is that the drawer module utilizes a 20mm component (MNS is 25mm); the cabinet adopts a push mechanism, that makes the procedure more convenient and also flexible. The MNS closet can be operated both sides, and a solitary cupboard can hold 36 loops (with 1/4 drawers) at most, while the GCS can be up to 22. The material used in the MNS cabinet is aluminum-zinc layered, fully set up framework, no post-processing (galvanizing) is required. The horizontal busbars of MNS and also GCS are separated from the front left cabinet device and also the front right cable television outlet area with dividers. Their upright busbars are put together in flame-retardant plastic practical boards to be much more reliable. The distinction is that GCS can only have 1/2 cabinet a minimum of, MNS has 1/4 cabinet, MNS cabinet has an additional interlocking mechanism, and also GCS just has the switch itself.
