在發電廠、變電站、大型工廠等電力系統中，存在一個不起眼卻至關重要的「連接件」—— 匯流排伸縮節。它專門用於連接兩段匯流排，是電力傳輸鏈路裡不可或缺的一環，由中間的軟銅帶與兩端的導體構成，不同部位採用具針對性的絕緣處理方案 —— 中間的軟銅帶採用熱縮套管進行絕緣，而兩側的導體則運用眾孚的核心技術「環氧樹脂流化絕緣技術」。其核心作用堪比人體的關節：當匯流排因通電發熱、環境溫差而出現熱脹冷縮，或是設備運行過程中產生振動位移時，中間的軟銅帶能靈活地「伸縮變形」，補償這些位移量，從而避免匯流排被拉斷、扭曲；與此同時，兩端的導體則負責保障電流持續穩定地傳輸。In power systems such as power plants, substations, and large-scale factories, there is an unassuming yet crucial "connector" - the bus expansion joint. Specifically designed to connect two sections of busways, it is an indispensable component in power transmission links. Composed of a flexible copper strip in the middle and conductors at both ends, different parts adopt targeted insulation solutions: the middle flexible copper strip is insulated with heat-shrinkable sleeves, while the conductors on both sides utilize Optimus's core epoxy resin fluidized insulation technology.Its core function is comparable to that of human joints: when busways undergo thermal expansion and contraction due to heat generated by energization or ambient temperature differences, or when vibration-induced displacement occurs during equipment operation, the middle flexible copper strip can flexibly "expand, contract, and deform" to compensate for such displacements. This prevents busways from being pulled apart or twisted, while the conductors at both ends ensure the continuous and stable transmission of electrical current.
導體核心絕緣：環氧樹脂流化技術加持，防護力拉滿Conductor Core Insulation: Enhanced with Epoxy Resin Fluidized Technology for Maximum Protection
傳統匯流排伸縮節的絕緣處理常存在「一刀切」的問題，不論是導體還是軟銅帶，多半採用熱縮套管或絕緣帶包紮。這類方式看似簡單，卻暗藏隱憂：一方面，包紮工藝容易產生縫隙，水分、灰塵等雜質易於侵入，導致絕緣層老化失效，進而引發短路風險；另一方面，針對導體部位的絕緣，傳統材料在耐候性、抗腐蝕性能上有所不足，面對沿海鹽霧、高溫高濕等極端環境時，短短十幾年就可能出現損壞，需頻繁停機更換，不僅增加維運成本，還會影響生產進度。Traditional insulation treatments for bus expansion joints often suffer from a "one-size-fits-all" issue. Whether for conductors or flexible copper strips, heat-shrinkable sleeves or insulating tape wrapping are commonly used. While this method seems simple, it hides potential risks:On one hand, the wrapping process tends to create gaps, allowing impurities such as moisture and dust to infiltrate. This leads to aging and failure of the insulation layer, thereby triggering short-circuit risks.On the other hand, traditional materials used for conductor insulation are insufficient in weather resistance and corrosion resistance. When exposed to extreme environments such as coastal salt spray, high temperature, and high humidity, damage may occur in just over a decade, requiring frequent shutdowns for replacement. This not only increases operation and maintenance costs but also disrupts production schedules.
眾孚環氧樹脂流化絕緣技術，從根源上解決傳統導體絕緣的短板。其工藝具有極強針對性：首先將導體精准加熱至特定溫度，接著浸入處於流化狀態的環氧樹脂粉末中，粉末會緊密貼合導體表面，均勻包裹每一處細節，固化後形成一層無縫無隙的絕緣層，就如同為導體「穿」上一件量身訂製的密封防護衣。Optimus's epoxy resin fluidized insulation technology fundamentally addresses the shortcomings of traditional conductor insulation. Its process is highly targeted:First, the conductor is precisely heated to a specific temperature.
Then, it is immersed in epoxy resin powder in a fluidized state. The powder adheres tightly to the conductor surface, wrapping every detail evenly.
After curing, a seamless insulation layer is formed, like a "tailor-made sealed protective coat" for the conductor.
這層導體絕緣層的性能可謂相當紮實：防水能力達到 IP66 防護等級，即便處於潮濕環境中，甚至短暫浸水，也能確保絕緣性能穩定，其 5kV 水中耐壓測試結果，遠超傳統產品 2.5-3.75kV 的標準；阻燃性能更能經受嚴苛考驗，面對 1300℃高溫火焰直接灼燒 10 秒，絕緣層依舊完好無損，且散熱效率優異，正常運行時表面溫度低，可避免燙傷風險。無論是南方潮濕的電廠、戶外淋雨的配電設備，還是化工車間的腐蝕性環境，導體部位的絕緣都能穩如泰山。The performance of this conductor insulation layer is outstanding:
Waterproof capability: It meets the IP66 protection level. Even in humid environments or brief water immersion, it can ensure stable insulation performance. The test result of 5kV underwater withstand voltage far exceeds the 2.5-3.75kV standard of traditional products.Flame retardancy: It can withstand rigorous tests. When directly burned by a 1300℃ high-temperature flame for 10 seconds, the insulation layer remains intact.Heat dissipation: It boasts excellent heat dissipation efficiency, with a low surface temperature during normal operation, avoiding scalding risks.Whether in humid power plants in southern China, outdoor rain-exposed power distribution equipment, or corrosive environments in chemical workshops, the insulation of the conductor part remains extremely stable.
軟銅帶適配絕緣：熱縮套管精准匹配柔性需求Insulation for Flexible Copper Strips: Heat-Shrinkable Sleeves Precisely Matching Flexible Requirements
針對承擔伸縮變形核心任務的中間軟銅帶，眾孚選用熱縮套管作為絕緣方案，此項選擇充分契合其功能特性。軟銅帶需頻繁應對匯流排的伸縮與振動，對絕緣層的柔韌性要求極高，而熱縮套管具備優良的彈性與伸縮性，能緊密跟隨軟銅帶的變形且不產生裂縫，確保在動態工作狀態下始終維持有效絕緣。與此同時，眾孚所選用的高規格熱縮套管經過嚴格篩選，擁有一定的耐老化與抗磨損能力，可與導體的環氧樹脂絕緣形成互補，共同建構起全面的絕緣防護體系。For the middle flexible copper strip, which undertakes the core task of expansion and contraction deformation, Optimus selects heat-shrinkable sleeves as the insulation solution - a choice that fully adapts to its functional characteristics. The flexible copper strip needs to frequently cope with the expansion, contraction, and vibration of busways, requiring extremely high flexibility of the insulation layer. Heat-shrinkable sleeves possess good elasticity and extensibility, enabling them to closely follow the deformation of the flexible copper strip without cracking, thus ensuring effective insulation is maintained at all times during dynamic operation.Meanwhile, the high-specification heat-shrinkable sleeves selected by Optimus undergo strict screening, featuring certain aging resistance and wear resistance. They complement the epoxy resin insulation of the conductors, jointly building a comprehensive insulation protection system.
