內置膠泥冷縮管的優點

內置膠泥冷縮管的優點

冷縮管相信使用的人都已經瞭解其優點有很多,比如密封防水、耐UV,比如其材質分為三元乙丙橡膠和矽橡膠材質等等,介紹一種內置膠泥冷縮管及其優點!


我們來瞭解非內置膠泥冷縮管的特點。常規冷縮管的性能優勢:

1.抗拉強度大、斷裂伸長率高、抗撕裂強度高、有著獨特的配方;

    對電纜握緊力極大、耐用抗老化、耐穿刺和摩擦、適用電纜截面積範圍特別廣,通訊冷縮管一般收縮比在5倍以上,電力行業冷縮管在4倍以上,有著強悍的收縮性能,獨特的柔軟富有彈性性能。

2.內置膠泥冷縮管獨有的特性再加上內部可以填充密封膠泥,在原有的性能上又有了一定的提升。

內置膠泥冷縮管普遍使用於戶外RRU(室外設備)接頭、天線接頭、信號發射設備連結頭、饋線對接頭、室外分系統接頭,以及同軸電纜和超柔電纜使用。安裝方便、快捷,是熱縮管和膠帶都替代不了的必須品,在使用時只要對準位置輕輕抽拉內層的環形芯繩(即支撐條),便可以迅速收縮到包覆體上,一次性成型安裝,極小的安裝控制項均可操作安裝,使用中的冷縮管抱緊力和載體共同呼吸,命運同體。

3.內置膠泥冷縮管是由三大部分組成:橡膠管+膠泥+高強度環形支撐條(芯繩);

    a.矽膠管:材料回彈力更大、防水效果極好,套在電纜或者產品上有著恒久的徑向收縮力;

    b.膠泥:不會凝固也不溢膠,流動密封可靠性高,兩頭管壁內壁密封,防雨水浸入;耐老化,耐氣候,使用壽命長;

    c.支撐條:不易垮塌(俗稱爆管),內外表面光滑美觀,抽取均勻,冷縮管可流暢收縮。


冷縮管使用說明

    內置膠泥冷縮管是通過鋼絲擴張機器設備擴張在支撐條上製成的,在原有的優質冷縮管兩端增加膠泥結構,並在套管永久的徑向收縮壓力作用下,讓矽膠管和電纜之間形成嚴密結構的新型基站防水產品,非常適合小空間及密集接頭處操作,也是國內外目前比較理想、成熟和可靠的通訊通信電纜防水解決方案。

    對於內置膠泥冷縮管,可以說普通冷縮管具備的優點內置膠泥都具備,而且在在其基礎上還作了延伸,達到雙重保障。

    用刀割開矽膠管內置膠泥觀察膠泥在支撐條上有無殘留;

    500%擴張率的情況下100烘烤半年時間觀察抗撕裂表現割口有沒有蔓延情況。


注意事項

因為冷縮管是物理擴張,所以在運輸當中切勿摔壓,以免爆管情況的發生;

安裝時一定要對準位置一次成型,若有偏差也不能重新利用。


Advantages of built-in clay cold shrink tubing

Cold-shrink tubing believes that people who use it already know a lot about its advantages, such as sealing waterproof and UV-resistant. For example, its material is divided into EPDM rubber and silicone rubber material. It introduces a built-in glue cold shrink tube and its advantages!


Let's take a look at the characteristics of non-built-in glue shrink tubing. Performance advantages of conventional cold shrink tubing:


1. High tensile strength, high elongation at break, high tear strength, and unique formula;

The cable has strong clamping force, durable anti-aging, puncture resistance and friction, and the cable cross-sectional area is particularly wide. The communication shrinkage tube generally shrinks more than 5 times, and the power industry shrinks more than 4 times, which has strong shrinkage. Performance, unique soft and elastic properties.

2. The unique characteristics of the built-in clay cold-shrinkable tube, together with the internal filling of the sealant, have a certain improvement in the original performance.

Built-in clay cold-shrink tubing is commonly used in outdoor RRU (outdoor equipment) joints, antenna joints, signal launch equipment joints, feeder-to-connectors, outdoor sub-system joints, and coaxial and super-flexible cables. The installation is convenient and fast, and it is an essential product that can not be replaced by the heat-shrinkable tube and the tape. When using, the inner core ring rope (ie, the support bar) can be gently pulled at the alignment position, and the body can be quickly shrunk onto the cover body. , one-time molding installation, minimal installation control items can be operated and installed, the cold shrink tube in use and the carrier to breathe together, the fate of the same body.

3. Built-in clay cold shrink tube is composed of three parts: rubber tube + clay + high strength annular support rod (core rope);

a. 矽 hose: the material has greater resilience, excellent waterproof effect, and has a long-term radial contraction force on the cable or product;

b. Mud: It will not solidify or overflow, and the flow sealing has high reliability. The inner wall of the two tubes is sealed, and the rainwater is immersed; the aging resistance, weather resistance and long service life;

c. Support bar: not easy to collapse (commonly known as squib), the inner and outer surfaces are smooth and beautiful, the extraction is uniform, and the cold-shrinkable tube can be smoothly contracted.

Cold shrink tube instructions

The built-in clay cold-shrinkable tube is made by expanding the steel wire expansion machine on the support strip, adding the cement structure at both ends of the original high-quality cold-shrinkable tube, and allowing the silicone tube and the tube under the permanent radial contraction pressure of the sleeve. The new base station waterproofing product with tight structure between the cables is very suitable for operation in small space and dense joints. It is also an ideal, mature and reliable communication and communication cable waterproofing solution at home and abroad.

For the built-in clay cold-shrinkable tube, it can be said that the ordinary cold-shrinkable tube has the advantages of built-in cement, and it has been extended on the basis of it to achieve double protection.

Use a knife to cut the glue inside the rubber tube to observe whether the glue has residual on the support strip;

In the case of 500% expansion rate, the tear resistance was observed at 100 ° C for half a year.



Precautions

Because the cold-shrink tubing is a physical expansion, do not drop the pressure during transportation to avoid the occurrence of a squib;

When installing, be sure to align the position once and form it. If there is any deviation, it cannot be reused.
