What is Dyneema?

UHMW POLYETHYLENE ROPE Dyneema rope is the highest strength of the current cable. Using Dyneema Dyneema high-strength polyethylene fiber, and then use the line to strengthen the process made of a super-smooth and sensitive rope. The surface of the cord body is lubricated by a factor which improves the coating on the surface of the cord. The smooth coating makes the cord durable and durable in color to prevent abrasion and discoloration. The successful development of the cable rope has led to the application of traditional wire rope in various occasions, such as the United States, Western Europe, Japan and other countries in the world is widely used in (ship mooring (civil, military), ship, Superior performance has been fully reflected.

The main performance characteristics of Dyneema rope：

High impact strength: strong high-quality steel is more than 10 times. High modulus: second only to premium carbon fiber. Light weight: density is less than water, can float on the water, than the same diameter of the wire rope light 87.5% or so. Good insulation properties. Lower unit length weight (Dyneema rope diameter and strength can be done and the same rope, but its weight is only 15% of wire rope). High-strength high-modulus polyethylene fiber is very good physical properties. Because of the high crystallinity, and is not easy to react with chemical chemical groups, so water, moisture, chemical corrosion, UV resistance, without the need to deal directly with the performance of UV resistance in the construction of the line more and more widely. High-strength high-modulus polyethylene fiber melting point between 144 ~ 152 ℃, Dyneema rope can be -150 ℃ to 70 ℃ (1), high-strength high-modulus polyethylene fiber with a high wear resistance, not only high modulus, and soft, have a longer bending life, , A short period of exposure to high temperature environment will not cause serious performance degradation, but continued friction caused by high temperature will reduce the strength of Dyneema rope.

Application of Dyneema rope：

Dyneema rope due to its superior performance, can be used in all directions. High-quality tow rope, high-strength traction rope. High intensity, light weight, easy to operate. Although the one-time investment is higher, but as long as the rope to maintain properly, its service life is 2-3 times the other rope. Heavy-duty ropes used in fishing and coastal industries. Sailboats, sailboats, sailboats, hoists, cable sling, string, gliding rope, sailboat, sailboat, sailboat, sailboat, sailboat, marine rescue system, Umbrella cable, climbing cable, Zhang Fan rope, shooting with a bow string and so on. Navy with rope, rope, paratroopers with the umbrella cable and other sail rope, helicopter slings, rescue and army and armored forces, a variety of sails, motorized with strong rope, because of its high strength, small diameter, weight Light, easy to carry and the advantages of operation, in many ways are suitable for use Dinima rope. Strong wire traction rope and Dyneema rope is commonly used in the construction of high-strength insulation rope, especially in the installation of important spans of the protective system, the higher environmental protection requirements in dense forest areas and has a complex or important to be crossing the line Engineering line process, its application is more frequent.

Advantages of the Dyneema Cord in the Power Grid Construction：

Dinima rope in the power grid construction process, what are the benefits? To understand its benefits, is conducive to our more rational use of Dinima rope:

1) In the difficult areas with the operation of loading paragliding, remote control airships, helicopters, etc. for the first line, the breaking force close to a ton of Dyneema electric traction rope diameter of only 3mm, weighs only 4.5 grams per meter. Has been more and more widely used. Such as: Taizhou Bridge primary line and secondary traction.

2) with a heavy-duty Dyneema electric traction rope once cast, once the cable traction over the Yangtze River, the Yellow River. Cable floating on the water, such as diameter and strength of the same cable, this method greatly improves the inter-river line efficiency.

3) in the live across the security network used as a carrier cable and traction cable, as Dyneema electric traction rope light weight (such as the strength of the unit length, weight only cable 1/8 ~ 1 / 10. And good insulation , Has passed 640Kv pressure test). Dyneema electric traction rope has been widely used in cross-over projects. In the balance across the line, tower, insulation, hoisting, tower equipment, safety rope and other applications, to protect the safety of construction equipment, improve the efficiency of construction.

Dyneema rope of the five major performance advantages：

Dyneema rope of the five major performance advantages, the more in-depth understanding, the more able to play the maximum performance of Dyneema rope:

1) Dyneema rope high tensile strength can effectively improve the bearing. The low elongation can effectively control the sag, so that the load-bearing cable in the case of the load, sag down as small as possible, to ensure that the closure device with live power line clearance to meet the safety requirements.

2) Dyneema cord insulation and moisture-proof performance can be guaranteed in the live across the construction process of personal and equipment safety.
3) The jacketed Dyneema rope is not affected by the breeze vibration, there is no broken stock and strength reduction.
4) Dinima rope material light, the same breaking strength under the conditions of tension, Dinima rope per meter weight of only 15% of wire rope, the use of Dyneema rope is conducive to reducing labor intensity and improve work efficiency.
5) Dyneema rope good resistance to bending fatigue, wear resistance, weather resistance, anti-ultraviolet and anti-chemical corrosion and other characteristics, is conducive to recycling in the construction across the use.
