25號變壓器油
中海南聯(lián)25號變壓器油是采用加氫原料經(jīng)過精密蒸餾切割、精制,加入抗氧劑調(diào)合而的產(chǎn)品它是用于330KV以下的變壓器及類似要求的電器設(shè)備,用于變壓器及油浸開關(guān)的絕緣油,也可用于其它電氣絕緣油的冷卻介質(zhì)。它的性能優(yōu)點為優(yōu)異的電氣絕緣性能,擊穿電壓高、介質(zhì)損耗因數(shù)小,可有效防止高壓電場下的放電現(xiàn)象和功率損失;良好的熱安定性和氧化安定性,可防止使用過程中形成酸和油泥,延長電氣設(shè)備的使用壽命;較低的粘度,提供有效的冷卻性、熱傳遞性及低溫啟動性;環(huán)烷烴和方向烴含量適宜,保證溶解電氣設(shè)備運行過程中形成的油泥而避免破壞絕緣材料和影響傳熱;環(huán)境友好,不含任何多氯聯(lián)苯。

變壓器油非常容易受潮氣、各種固體顆粒、纖維等污染,因此,變壓器油必須注意保持干燥和清潔。儲存容量必須專用,嚴(yán)禁接觸發(fā)動機(jī)油、液壓油和齒輪油等潤滑油,并且盡量放置在戶內(nèi)或可控制的氣候環(huán)境下。
好質(zhì)量“油”我創(chuàng)造,好產(chǎn)品自然締造,產(chǎn)品遍及華南及全國各地,為華南地區(qū)最大白油銷廠家之一。
以客戶為中心,精心打造品牌服務(wù)是中海南聯(lián)人的經(jīng)營宗旨,“高效、求實、創(chuàng)新”的中海南聯(lián)人誠邀你攜手并進(jìn),乘風(fēng)破浪,共創(chuàng)輝煌。
