瓦楞紙板 CORRUGATED BOARDS
瓦楞紙板是小型變壓器的一種常用油隙絕緣，它的優點是裝配簡單，改善了固體絕緣材料在油道中分配，與在徑向均勻配置撐條相比，在瓦楞紙板的油道中，固體絕緣分布非常均勻，不存在與電場垂直的平面，因此，油道強度可提高15%左右，而不喪失可靠性，我公司采用熱壓成型等工藝生產的瓦楞紙板，具有如下優點：
---較高的機械強度
---優良的電氣性能
---形狀穩定，尺寸準確
Corrugated boards are commonly used as oil gap insulating for transformer. Its advantage is in assembly. It improves the distribution of oil channels in solid insulation material comparing with the strips radially arranged evenly in the oil channel of corrugated board. The solid insulation is very even. There is no surface which is perpendicular to electric field, therefore it can increase the strength of the oil channels by 15% without losing its reliability. The corrugated boards in our company are produced by hot pressing. They have follow advantage:
--High mechanical strength
--Superior electric character
--Stability shape and, accurate size
