When designing a waterproof distribution box, the protection level is the main content of the key design scheme. Sometimes, in order to highlight this point, the waterproof distribution box is also specially formulated with a protective protrusion layer to effectively avoid the penetration of water or dust. Secondly, the influence of material selection on the effect of waterproof distribution box should be considered.
1. Waterproof distribution box, how to make it waterproof
1. The sealing ring plays an important role in the protection of the waterproof distribution box. The sealing ring plays a vital role in protecting the protection level of the waterproof distribution box.
2. When the power distribution cabinet is used for a long time, the continuity of the protection level depends on the characteristics of the sealing ring. When foaming, the polyurethane seal will be firmly held in place. EPDM materials, with their excellent resistance to organic chemical corrosion, provide excellent protection against most widely used chemical levels.
3. The door of the waterproof distribution box can be opened single or double, the opening angle can reach 130 degrees, and the left and right can be disassembled and replaced to complete the regulation of the left and right doors.
4. Protect against fouling. Polyurethane material foam sealing strip, reliable sealing.
5. The two sides of the door are welded with vertical strips, which are used for the installation of matching holes. M4 self-tapping screws for quick and better assembly of cable wire harnesses, wire sleeves, etc.
6. The rear cover of the bottom punch enters the wire, and the rear cover can be removed in advance and punched, and the sealing ring can be installed.
7. Protection class: IP54
8. Surface treatment of waterproof distribution box: degreasing, pickling, phosphating, outdoor waterproof electrostatic plastic powder
lighting box
Second, the characteristics of waterproof distribution box
1. The waterproof distribution box has the characteristics of anti-fouling, acid resistance, alkali resistance, beautiful appearance, stable quality, non-conductive insulation layer, anti-collision and no wrinkle and so on.
2. Full insulation protection, choose metal materials, cold-rolled sheets, electrostatic powder coating or stainless steel boxes; PCs with different displacement coefficients can use monitoring windows, which are flexible and safe.
3. PU foam sealing strip ensures that the box can achieve IP protection level 56; hot-dip galvanized mounting plate can also be used for wiring outside the box;
4. The double-layer maintenance groove at the box mouth can not only reinforce, but also prevent dirt and water from entering the box when the door is opened.
