Introduction:
LWSMC series electrical cabinet is a new type switch box, it is made of glass fiber reinforced polyesters.With same strength with metal cabinet but only 1/3 weight of metal cabinet.LWSMC series electrical cabinet designed to be assembled with various electrical componets according to different control function requirement.
waterproof electrical SMC distribution box
1, in the relative humidity close to more than 100% of the special wet places and corrosive gas or steam places should be selected protective type;
2, in the relative humidity is not more than 75%, and no dust, no corrosive gas or steam, no flammable and explosive material risk is small, the low-voltage distribution box can be selected open type;
3, in the flammable liquid and suspension, accumulation of flammable powder or flammable fiber H-1 class, H-2 class fire danger places, should choose dustproof;In the solid combustible material H-3 fire danger places, can protect the type;
4, can produce a lot of dust in dusty places, should choose dustproof waterproof electrical SMC distribution box;
5. Flameproof, explosion-proof, ventilated and inflatable low-voltage distribution box should be used in places with gas or vapor explosion mixture and Q-1 level places that can form a leaky mixture under normal circumstances.Any explosion-proof type can be used in Q-2 level places where explosive mixtures can be formed under normal circumstances.Sealed type can be used in Q-3 class places that cannot be formed under normal circumstances, but can form explosive mixture under abnormal circumstances, but the possibility is small.
IP protection level is usually a factor we need to consider, dustproof and waterproof, of course, in some special cases we also need to consider whether the explosion-proof ability is strong, the above is from five points to consider how our low-voltage waterproof electrical SMC distribution cabinet should be selected.
