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 refers to a full collection of power distribution tools put together from primary devices and also additional tools according to a certain circuit plan. It is used to regulate and secure circuits and also equipment. The framework of the switchgear is approximately similar, mostly split into busbar room, circuit breaker space, second control area (instrument area), feeder area, each space is normally separated by steel plates. low-voltage withdrawable switchgear 1. Understanding of circulation box (cabinet). GCK, GCS, MNS are low-voltage withdrawable switchgear; GGD, GDH, PGL are low-voltage taken care of switchgear; XZW is an extensive distribution phosphate pretreatment equipment box; ZBW is a box-type substation; XL, GXL are low-voltage power distribution cabinets as well as construction site boxes; JXF is an electric control box; PZ20 and PZ30 series are terminal lights distribution boxes; PZ40 and also XDD( R) are electric meter measurement boxes. 2. The result of low-voltage power circulation cabinets. ( 1) It is practical to set up the power supply fairly. ( 2) When the line falls short, it is advantageous to manage the extent of the fault and also it is practical to swiftly find the mistake point and also eliminate it in time. ( 3) It is practical to prepare circuit maintenance in pieces, without large-scale power blackout. ( 4) Various defense devices such as integrates to stop short circuits and also air switches to prevent overload can be easily placed in the power distribution cupboard. 3. The structure of the low-voltage power circulation closet. ( 1) The power distribution cabinet generally consists of: circuitry terminals, different buttons, defense tools (air switches, merges, etc.), determining tools (voltmeter, ammeter, cycle meter, etc.), measuring devices (active as well as reactive power) table). ( 2) There are numerous types of low-voltage power distribution cupboards, and also the elements are really different. Taking the power cupboard as an instance, from leading to base: blade button, present transformer, air switch, and also branch circuit breakers. TControl power distribution closet. 4. The material of each number of the power circulation cabinet model. GGD low-voltage power distribution cabinet: G-- low-voltage power circulation cabinet; G-- fixed installation as well as electrical wiring; D-- power cabinet;. GCK low-voltage power circulation cabinet: G-- cupboard framework; C-- withdrawable kind; K-- nerve center;. GCS low-voltage power circulation cabinet: G-- enclosed button cupboard; C-- withdrawable type; S-- Senyuan electrical system;. MNS low-voltage power circulation closet is an item manufactured according to the transfer innovation of Swiss
ABB firm. 5. The difference between GGD, GCS, GCK, MNS power circulation cupboard. GGD is various from the other three because it is a set type, while GCK, GCS, and also MNS are all drawer kind button cabinets. Each outlet unit of them is independent as well as each circuit will not influence each various other. GCS is a brand-new generation of drawer kind switch closet developed by Senyuan Company in the mid-90s with referral to ABB's MNS cupboard type. The major framework is similar to MNS, with the main bus bar behind. The difference from MNS is that the cabinet component utilizes a 20mm component (MNS is 25mm); the cabinet adopts a push mechanism, that makes the operation more convenient and also versatile. The MNS cupboard can be operated both sides, and also a solitary cupboard can hold 36 loopholes (with 1/4 drawers) at many, while the GCS can be approximately 22. The material used in the MNS closet is aluminum-zinc layered, completely assembled framework, no post-processing (galvanizing) is needed. The straight busbars of MNS and GCS are separated from the front left drawer system as well as the front right cord outlet compartment with dividings. Their vertical busbars are set up in flame-retardant plastic practical boards to be a lot more dependable. The distinction is that GCS can just have 1/2 drawer at the very least, MNS has 1/4 drawer, MNS cabinet has one more interlacing device, and GCS just has the switch itself.
