Description
Our Solid Insulated Ring Main Unit, metal enclosed electrical switchgear, Dry Type Cast Resine Distribution Transformer has won wide praise and all customers praise, for which we are deeply honored, and will not change the original will continue to struggle for the majority of customers. We integrate cultural concept into all aspects of production construction and quality management. Our company has a number of high-quality, professional staff.
Product details:
GCK type draw-out low-voltage switchgear, the main frame is made of KB (25mm modulus) steel, the material is cold-rolled steel plate, or aluminum-zinc plate can be used as required by the buyer.
GCK type withdrawable low-voltage switchgear, according to the content of GCK type scheme, compose various functional structural cabinets, and users can combine according to the primary system diagram.
Drawer cabinet structure, the height of the drawer installation part is 1800mm. At present, the height of the unit drawer is mostly 200mm. There are 6 types of drawer specifications. The cabinet can accommodate up to 36 drawers in 14 units. 18 drawers in 12 units and 9 drawers in 1 unit. This rule is combined by itself, the maximum allowable current in the drawer is 630A
There are 7 kinds of vertical busbar specifications in the drawer cabinet: 30x6, 40x6, 50x6, 60x6, 80x6, 100x6, 120x6
The cabinet structure meets the technical requirements of GCK low voltage switch cabinet.
The protection level of the switch cabinet is IP30-IP40
Structure description:
The cabinet body is a combined assembly structure, and the skeleton is assembled with KB profile (C profile). The horizontal bus is placed on the top of the cabinet, the top cover can be opened, the cabinet is equipped with a back door, and the outlet method adopts the rear outlet installation and maintenance to be more convenient. The cabinet protection level is IP3X-P4X, the drawer adopts three-station hand-pull and hand-type two push mechanisms, plastic switch 63, 100, 160, 250. Drawer adopts hand push mechanism; plastic switch 400 , 630 type, the drawer adopts a hand-operated push mechanism; other schemes can also be adopted as required by the demander. The primary plug-in adopts a new type of no valve, which is more reliable. The rated current of the unit loop is 630A and below, and the maximum current of the 12-unit drawer can reach 125A.
