Featured with small volume, large current carrying capacity, high withstanding voltage, reasonable structure, nice appearance, etc., this product has many superior properties such as flame retardant, withstanding high temperature, no water absorption, wetness prevention, perfect insulation, impact resistance, anti aging, etc..
Its cover plate is made of transparent material, assembled and disassembled conveniently, so, it attains the goal of transparence and visualization as well as reliable power utilization. |
| 三、 產(chǎn)品用途 Application |
該適用于各種表位計量的配套使用，安裝后不但解決了進戶線直接進裸銅排，造成電流小、不安全、不可靠、不方便等諸多事故隱患的問題，而且減少計量箱的成本。按產(chǎn)品的極數(shù)分為單極（1P）、單相（2P）、三相三線（3P）、三相四線（4P）；按出線分為一出、二出、三出、四出…二十四出等。
This product supports metering of various meter-position, after mounting, it not only avoids the problem of weak current, unsafe, inconvenience or other potential accidents caused by service-entrance wire entering into bare copper bar directly, but also cuts down the cost of metering box. It can be divided into single-pole (1P), single-phase (2P),
three-phase three-wire (3P), three-phase four-wire (4P) according to the pole number; it can be divided into one-outlet, two-outlet, three-outlet, four-outlet … twenty-four-outlet and so on according to the outlet wire condition. |
