distribution box plastic Introduction:
Made of strength ABS and PC material, the enclosure has beautiful appearance, high plasticity and doggedness. LWHA series distribution box is suitable for terminal boxes, distributionpanels.instrument boxes, electrical equipment boxes and control boxes. Moreover, it is simple and easy to use.
"Actually said is distribution box plastic distribution box aging line, aging line to a fixed number of year, can't normal use of the" distribution box brand head said, "in addition, the high temperature baking, sunlight and corrosive environment, will directly lead to shorten the life distribution box line, line insulation cracking, even black, decomposition, This will cause a short circuit, local heat, high temperature, melting insulation layer, ignited around combustible, and then cause a fire ". Both enterprises and individuals should pay attention to the fire caused by the aging of distribution box and circuit, and do some practical and useful measures to eliminate the fire hazard. And in the usual daily life, people want to check the house more electrical wiring is safe, try not to a network connecting lines, kitchen, toilet in the home also wet parts to line leakage protection, automatic air switch and fuse installation, it is forbidden to use alternative fuse copper wire, aluminum wire, household circuit encountered had better ask professional installation, Prevent fire hazard.
The Distribution Box Plastic testing is very important and before doing this test we need to check the megger or insulation tester. In the merger we can see a red wire and a black wire connect the red wire to the megger’s line terminal and then connect the black wire to the megger’s earth terminal. Then connect the two-port tips (short it), so while doing this the megger should display a zero valve, and if not there is a problem. The testing of the distribution box must be done by experienced personnel otherwise it could create a lot of problems certain circuit components in the distribution box could be damaged. Mostly while doing the testing of the distribution box the meter coils are damaged so the testing must be conducted by an experienced person. Also while doing the testing certain devices in the distribution box should be turned off like an RCCB.
