Steel , IP30 - Class , Protective Enclosure , Dry-Type Transformer, Accessory for transformer
Attractive and wearing-resistant protective enclosures are available to provide additional protection to transformer, and the protection level could be IP20, IP23 or higher.
The material is stainless steel plate, aluminum alloy plate and other suitable materials.
IP20 enclosure provides protection against the entrance of foreign objects with diameter exceeding 12mm and could withstand accidental shock.
IP23 enclosure, in addition to functions of IP20 enclosure, also provides protection against rainfall at a vertical angle of less than 60°. But the IP23 enclosure will reduce transformer's cooling capacity by about 5%~10%, therefore this must be taken into account when selecting enclosure for the transformer.
Cable support is supplied for HV(LV) incoming (outgoing) connections from bottom of enclosure.
Enclosure should be installed according to series no., plates with same series no. should be fixed together. Connection of net plate and groove, pattern plate and groove, should be fastened by M5x12 self-tapping screw. Two slots connection should be tightened by 3D contacts, M8 socket head cap screw as well as flat block. Between trislots, between two slots and trislot, connection by connecting board and a set of M8 external-hexagonal screw and nut.
Make an example of connection of front plate and left side plate. Connecting side is A1.
1:Upper net plate of front side and the middle door needs first installation. Connection of net plate and trislots is fastened by M5×12 self-tapping screw.
Upper center pillar of net plate connects to center pillar of the door with connecting board and set piece of M8 external-hexagonal nut.( Keep centralized, and align at both side)
2: Install front side and left side, firstly, connect the board between trislots. (Other sides are the same steps). As shown, 3D contact of A1 on left under side is connected with two slots of A1 on the front side, using M8 socket head up screw and flat block to tighten.
