絕緣插板是在鋁業(yè)電解槽短路口絕緣作用的，他可以根據(jù)材質(zhì)分為：SMC 絕緣插板環(huán)氧樹脂絕緣插板云母絕緣插板，下面就我公司生產(chǎn)的環(huán)氧樹脂絕緣插板作如下詳細(xì)介紹。

產(chǎn)品特性：

環(huán)氧樹脂插板是由環(huán)氧樹脂和玻璃布制成，型號為3240，在中溫下機(jī)械性能高，在高溫下電氣性能穩(wěn)定。適用于機(jī)械、電器及電子用高絕緣結(jié)構(gòu)零部件，具有高的機(jī)械和介電性能較好的耐熱性和耐潮性。耐熱等級B級（155度）。根據(jù)客戶的圖片加工成型。

表5垂直層向電氣強(qiáng)度

注：1 對90℃±2℃油中垂直層向電氣強(qiáng)度，可任選20s逐級升壓和1min耐壓試驗要求中的一種。對符合二者之一要求的材料，應(yīng)視其90℃±2℃油中垂直層向電氣強(qiáng)度是符合本標(biāo)準(zhǔn)要求的。 2 如果測得的試樣厚度算術(shù)平均值是介于表中兩厚度之間，則其指標(biāo)值應(yīng)從內(nèi)插法求取。如果測得的厚度算術(shù)平均值小于0.4mm，則其電氣強(qiáng)度指標(biāo)值取≥16.9MV/m。如果標(biāo)稱厚度為3mm，并且測得的厚度算術(shù)平均值大于3mm時，則其電氣強(qiáng)度的指標(biāo)值取≥10.2MV/m表6吸水性
