高電壓絕緣熱收縮套管

母排熱縮管使用前的注意事項

母排熱縮管使用前的注意事項

在使用熱縮母排保護套管時需注意那些事項?
    1、我們的母排熱縮管按耐壓可分為1kv母排熱縮管,10kv母排熱縮管,24 kv母排熱縮管,35kv母排熱縮管以及110kv母排熱縮管。熱縮套管有固定的收縮比例,同時熱縮套管的絕緣耐壓取決於收縮後的套管厚度,所以在選型上一定要按照產品說明書上規定的方法——不同尺寸的母排使用相應規格的套管。
    2、銅鋁母排在生產、存儲、搬運、搪錫的過程中容易造成表面刮傷,產生毛刺,熱縮套管在加熱收縮時主要是依靠巨大的內部應力以達到收縮目的,而且加熱狀態下的熱縮套管較軟。此時如果收在表面有尖銳毛刺的銅鋁母排上,熱縮套管會被劃傷,這樣母排熱縮套管即時開裂或運行一段時間後開裂。所以在加熱收縮前一定要檢查銅鋁母排有無毛刺並加以相應處理使銅鋁母排表面平滑。
    3、基於2項中所提及,在使用連續型母排熱縮套管前,當根據具體需要數量對套管進行裁剪時,必須保證切口平滑,不能出現鋸齒形的切口。
母排熱縮管的儲存與運輸:
    母排熱縮管在保管和運輸過程中要避免陽光直射或環境溫度超過60,當環境溫度超過60時,熱收縮產品可發生部分收縮。
    以上即為母排熱縮管使用時需要注意的幾點。母排熱縮管廣泛適用於電力系統、礦業、化工、石油、船舶、冶煉等行業變電站的匯流母線的絕緣防護,無溫升問題,不降低母線載流量,具有優異的絕緣性能、防腐蝕性能,良好的工藝特性,安裝方便,安全可靠等特點,是電力系統全工況綜合絕緣防護的首選。
下面我們進一步強化下母排熱縮管的主要功能:
    可以有效的杜絕變電站普遍存在的由老鼠、蛇、貓等小動物造成短路的電力事故。
    防止汙閃、雨淋、凝露等引發閃絡造成的電力事故。
    有效的防止帶電裸排所造成的人生傷亡事故。
    防止鹽霧及各種有害化學氣體對母線的腐蝕。
    特殊電氣(電器)接點部位的熱縮絕緣防護處理。
    防止單相對地短路和相間短路造成的電氣(電器)事故。


Precautions before use of busbar heat shrinkable tube

What should you watch out for when using a heat-shrinkable busbar protection sleeve?
1. Our busbar heat shrinkable tube can be divided into 1kv busbar heat shrinkable tube, 10kv busbar heat shrinkable tube, 24kv busbar heat shrinkable tube, 35kv busbar heat shrinkable tube and 110kv busbar heat shrinkable tube according to pressure resistance. . The heat shrinkable sleeve has a fixed shrinkage ratio, and the insulation withstand voltage of the heat shrinkable sleeve depends on the thickness of the sleeve after shrinkage, so the selection must be in accordance with the method specified in the product manual - the busbar of different sizes The corresponding size of the casing.
2. The copper-aluminum busbar is prone to surface scratching and burr in the process of production, storage, handling and tin-smelting. The heat-shrinkable sleeve mainly relies on huge internal stress to achieve the purpose of shrinkage during heating and shrinking, and the heating state. The lower heat shrinkable sleeve is softer. At this time, if the copper-aluminum busbar with sharp burrs on the surface is received, the heat-shrinkable sleeve will be scratched, so that the heat-shrinkable sleeve of the busbar is immediately cracked or cracked after running for a while. Therefore, before heating and shrinking, it is necessary to check the copper-aluminum busbar for burrs and treat them accordingly to smooth the surface of the copper-aluminum busbar.
3. As mentioned in the 2 items, before the continuous busbar heat shrinkable sleeve is used, when the sleeve is cut according to the specific number of requirements, it is necessary to ensure that the slit is smooth and the zigzag cut cannot be formed.


Storage and transportation of busbar heat shrink tubing:
The heat-shrinkable tube of the busbar should be protected from direct sunlight or the ambient temperature exceeds 60 °C during storage and transportation. When the ambient temperature exceeds 60 °C, the heat-shrinkable product may partially shrink.
The above are the points that need attention when using the heat-shrinkable tube of the busbar. Busbar heat shrinkable tubing is widely used for insulation protection of confluence busbars in substations of power systems, mining, chemical, petroleum, marine, smelting, etc. No temperature rise problem, no reduction of bus current carrying capacity, excellent insulation performance and corrosion resistance , good process characteristics, easy installation, safe and reliable, etc., is the first choice for comprehensive insulation protection of power system.
Below we further strengthen the main functions of the lower busbar heat shrinkable tube:
● It can effectively eliminate electric power accidents caused by short circuits caused by small animals such as mice, snakes and cats.
● Prevent electric accidents caused by flashover, rain, condensation, etc. caused by flashover.
● Effectively prevent life-related accidents caused by live bare platoons.
● Prevent salt spray and various harmful chemical gases from corroding the busbar.
● Heat-shrinkable insulation protection treatment for special electrical (electrical) contact parts.
● Prevent electrical (electrical) accidents caused by single short-circuit and phase-to-phase short circuit.
