Parallel strand cable/Suspension Bridge Cables
Introduction
Parallel strand cable/Suspension Bridge Cables is a cable composed of multiple steel strands parallel to each other. These strands are often twisted or braided together to form a strong yet flexible cable. Parallel strand cable is known for its high strength, durability and resistance to stretch. Suspension bridge cables play a huge part in bridge construction. They need to be strong and reliable in order to be considered for use. We produces extremely high quality suspension cables that can be relied on for many years of reliable use.
Besides, the substrate of steel strand cable system mainly adopts φ15.2mm orφ15.7mm, the standard strength of 1860MPa, the elastic modulus of 1.95 x 105MPa uses steel strand as cable base, the performance of steel strand meets the international standard requirements of EN10138, ASTM A416 and GB / T5224-2003.
Characteristics of Double-layer PE unbonded epoxy steel strand:
Steel strand according to the different forms of anti-corrosion is divided into two kinds of galvanized steel strand and epoxy coated steel strand surface anti-corrosion, after the surface anti-corrosion, and then through the corrosion oil outside the PE sheathed unbonded steel strand, and Hot-extruded PE protection of double PE unbonded steel strand in order to achieve better anti-corrosion performance.
Double-layer PE unbonded epoxy steel strand has the same protective function as other PE steel strand, mainly designed for the replaceable steel strand cable. The PE steel wire has a 2mm thick oil layer between the polyethylene layer C and the polyethylene layer d, reducing the friction between the two polyethylene layers and playing a replaceable role. The cable made of such PE strand can be replaced with a single PE strand.
No matter what kind of anti-corrosion steel strand, multiple steel strand together for wire weaving treatment, and then through double layer co-extruded HDPE equipment to extrude double layer PE sheath to become the steel strand finished cable. Our company produces galvanized steel strand finished cable, epoxy steel strand finished cable and all kinds of unbonded steel strand finished cable, suspenders, cable saddles, cable clamps of bridges stay-cable strands, etc.
Characteristics of the Self-anchored suspension Bridge
1.Removes the need for a giant anchor.
2.The main cable is anchored on the top of the bridge deck.
3.Innovative structure
4.Aesthetically pleasing exterior
5.Light weight
6.Load is uniformly distributed on the structural component.
7.Cost-effective raw material
8.Highly-competitive bridge design for small and medium spans
Applications
They are commonly used in applications that require strong and reliable cables, such as overhead power lines, suspension bridges and other structural applications. Parallel strands help distribute loads evenly, making the cable ideal for supporting heavy loads and resisting bending and torsional forces.
