Description of the use of wire rope

Steel wire made of high quality carbon steel, after repeated cold drawing and heat treatment can achieve high strength. Wet or open environment and other workplace can be galvanized steel wire twisted into the wire rope to enhance the anti-rust performance.

Steel wire rope in the industrial countries are standard products, according to the need to choose its diameter, the number of strands, the number of wires per strand, tensile strength and adequate safety factor, its specifications can be found in the relevant manual. In addition to the wear of the outer wire, the wire rope is gradually broken by the repeated bending of the pulley and the reel, so the ratio of the pulley or the diameter of the reel to the wire rope is an important factor in determining the life of the wire rope. Large ratio, steel bending stress is small, long life, but the body is huge. Must be based on the use of occasions to determine the appropriate ratio. The wear and tear of the surface layer of the wire rope shall be scrapped when the number of threads exceeds the specified value.

Wire rope is mainly used in the lifting, transport and other needs of high-strength rope in the transport.

Classification / wire rope editing

Wire ropes can be sorted by shape, level, status, etc.

 shape

1. Round wire rope

2. Woven wire rope

3. Flat wire rope

In accordance with the rope wire material classification:

1. Carbon steel wire rope, high-quality carbon structural steel wire as raw materials twisted from.

2. Stainless steel wire rope, made of stainless steel wire as raw material twist,

According to the surface of the wire rope classification:

1. Phosphor coated steel wire rope patented technology

       The phosphating film can make the surface of the steel wire more wearable and improve its anti-corrosion ability. The phosphating film porous structure can increase the storage capacity of the grease on the surface of the rope and reduce the friction factor to promote the sliding and delay The occurrence of micro-damage on the surface of the wire, inhibit the initiation of fatigue microcracks, thus greatly extending the service life of wire rope [1].

     Will be made of wire rope phosphating treatment, the priority of the use of manganese or zinc-manganese phosphate, steel wire is not carried out after any drawing, direct use of phosphating steel wire twist wire rope, the phosphate coating to make the surface more wear , The use of phosphating wire rope life is 2-3 times the smooth steel wire rope, wire rope fatigue performance significantly improved [2].

2. Galvanized steel wire rope, galvanized steel wire twisted, including hot-dip galvanized and electro-galvanized two methods, the thicker the galvanized layer, the better the anti-corrosion effect.

3. Apply a wire rope to a layer of plastic, including polyethylene, polypropylene and polyurethane, in the outer layer of wire rope or strand.

4. Smooth steel wire rope, the use of smooth steel wire twisted from the system, that is, after the cold drawn steel wire rope, without any surface treatment directly twisted steel wire rope

Definition and construction of wire rope The wire rope is an important part of the cable seals, let us through this article to get a preliminary understanding of it. A definition With a number of strands or more stranded wire twisted into a flexible rope, wire rope is twisted by the multi-layer wire, and then to the core as the center, by a certain number of shares twisted into a spiral rope. In the material handling machinery, for lifting, pulling, tensioning and carrying the use. The high strength of the wire rope, light weight, work smoothly, not easy to break the whole root, reliable work. Second, the structure 1. Wire: wire rope to bear the role of load, its performance is mainly determined by the wire. Steel wire is made of carbon steel or alloy steel by cold drawing or cold rolling round (or shaped) wire, with high strength and toughness, and according to the use of different environmental conditions on the wire surface treatment. 2, the core: the core of the main role is to increase the rope elasticity and toughness, lubrication of steel wire, reduce friction, improve the service life of wire rope. Commonly used cord types include organic fibers (such as hemp, cotton), synthetic fibers, asbestos core (high temperature conditions) or soft metals and other materials.

Cable seals

Security seals are mechanisms used to seal shipping containers in a manner that provides tamper evidence and several amount of security. Such seals will help you to detect theft or contamination, either accidental or deliberate. Security seals are usually employed to secure truck trailers, vessel containers, chemical drums, airline duty-free trolleys and utility meters. Typically they are really considered an affordable way of providing tamper evidence of intrusion into sensitive spaces.

Security seals can be split into two main groups: single use and reusable. Single use seals are typically manufactured from plastic or metal, and also the used material and production technology is key with their security level. Reusable seals usually are electronic or mechanical as opposed to just manufactured from plastic, and if purely plastic, one part is reusable. Electronic and mechanical seals are typically used for the transportation industry, with seal fixed to the back of trucks, trailers and shipping containers. A reusable mechanical or electronic seal could be fitted for the rear or loading doors, extending a cable from itself through fixing points in the doors, and whenever sealed creating a unique number which is logged. Once the door is next opened this number changes, thus it provides tamper evidence to the load.

The requirements for specific security degree of seals are defined during the ISO 17712. The seals that are part of the High security level and Security level are called "barrier seals". They are created from different metals or metal alloys, meaning that they might require special tools to generally be opened, for example bolt cutters or pliers. Cable seals and bolt seals also fall into this category. Made to deter opportunistic theft of high value goods, in addition, they is sometimes branded and numbered to further improve tamper resistance and provide excellent security for containers. The seals that are within the Indicative level regarding ISO 17712 are made from plastic or thin metal.

Cable seals permit more versatile application, while they have variable entire locking mechanism limited only through the cable length. Typical applications include sealing trucks and railway cars transporting valuable commodities. An inside locking mechanism prevents the cable from being retracted. Most cable seals are considered security or high security level as to ISO 17712.

All ISO 17712 compliant seals are numbered on seal body and head, to stop substitution of either part. This is usually done using laser marking, which should not be rubbed off.

Ball seals are typically used for securing trucks. They comprise of metallic strip by using a punched hole, attached with a housing section. As soon as the strip is bent and threaded throughout the hole, a ball into the housing section locks it in position. Most ball type seals belong simply to the indicative level about ISO 17712.

Roxtec Cable Seals - Sealing Cable Ducts In Substations Under Running Water Conditions (VIDEO) - Thorne & Derrick

T&D are Approved Distributors for Roxtec Cable Seals - contact T&D for Roxtec quotations, delivery and technical support.

Roxtec are the world leading manufacturer of cable and pipe sealing transits to protect against water ingress, gas migration and fire spread. The following article by Gavin Cornall (Divisional Manager Construction, Power & Process at Roxtec UK & Ireland) discusses cable sealing applications during running water or “flood” conditions.

Firstly, running water presents a major sealing issue for the installation of mastic type seals, curing and drying is almost impossible. This can place “stress and strain” on work programme completion times, especially approaching handover phase.

Secondly, this applies to any solution used to seal large power cables whether in a one cable, one duct format or passing in a trefoil formation through a larger duct. Such as 11kV and 33kV power power cables feeding MV substations. The ability of the cable seal to provide reliable operation under high water pressure is essential – the flexibility of the cable seal to be installed during running water conditions is equally crucial.
