| 三、 产品用途 Application |
该适用于各种表位计量的配套使用，安装后不但解决了进户线直接进裸铜排，造成电流小、不安全、不可靠、不方便等诸多事故隐患的问题，而且减少计量箱的成本。按产品的极数分为单极（1P）、单相（2P）、三相三线（3P）、三相四线（4P）；按出线分为一出、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. |
