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.
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.
