![]() The type of strand in this specification is 7-wire strand and consists of a center wire with a 6-wire layer concentrically twisted around it with a uniform pitch of not more than 16 times the specified nominal diameter of the strand.Stranding is sufficiently close to ensure no appreciable reduction in diameter when stressed to 10% of the specified strength. All wires are stranded with uniform tension. A left lay is defined as a counterclockwise twist away from the observer. Unless otherwise specified, the wire strand has a left lay.The slab zinc from which the coating is derived will be any grade of zinc conforming to ASTM B6 “Specification for Zinc (Slab Zinc)”. It is of such quality and purity that when drawn to the specified size and coated with zinc, the finished strand and the individual wires will be of uniform quality and have the properties and characteristics as prescribed in ASTM A475. The base metal is steel made by the open-heart, basic oxygen, or electric furnace process. The wire strands covered in this specification are commercially known to be 6M, 10M, and 16M all of which are seven-wire (7-wire) strand. The guy wire is of extra high strength grade based on ASTM A475 Standard Specification for Zinc-Coated Steel Wire Strand”. Chapter 7: Frequently Asked Questions (FAQs).Chapter 6: Galvanized Steel Wire for Sale.Chapter 4: Guy Wire Packing and Marking.Chapter 3: Guy Wire Dimensional Specification.Chapter 2: Guy Wire Physical Specification.Length of wire in finished coil: Standard Single wire, after stranding, wrapped on a mandrel 8 times its own diameter Singe wire, before stranding, wrapped on a mandrel 4 times its own diameter Minimum weight of zinc coating after stranding Minimum weight of zinc coating before stranding Minimum percent elongation at rupture after stranding Minimum percent elongation at rupture before stranding Maximum tensile strength of individual wires ![]() Minimum ultimate tensile strength of individual wires Nominal overall diameter of stranded staywire If you have any inquiries, please do not hesitate to contact us. Each wire will be completely and smoothly galvanized before stranding.Īs a leading guy wire manufacturer and supplier, Rax Industry can support you with all sizes of stay wire, We also can do OEM or ODM for you. Stay wire is manufactured perfectly and stable to withstand environmental stress during installation and throughout its lifetime.Īll the galvanized steel wire is free from any scale, inequalities, spills, splits, or other defects. All of these stay accessories make up the pole line and telephone line to stable the pole and conductors. Guy wire is assembled with guy clamp, stay thimble, stay rod, stay pole bracket, anchor rod, and turnbuckle stay set. Guy wire is also called stay wire or messenger wire. failing load of 88 kNGuy wire is a tension cable stranded by a few wires which are approximately circular in section and contain no weld, joint, or splice, it is lightweight and strong enough to stabilize and secure poles, towers, and other free-standing structures, especially in utility, antenna, and communications industries. B type for the same 240/415V with min.A type for 240/415V with minimum failing load of 44 kN.Guy Insulators can also be effectively used for dead end on medium voltage lines. ![]() Two C type guy strain Insulators are normally used in series for 33 kV lines. A type for 240/415V with minimum failing load of 44 kN Three types of guy strain insulators are generally used for rural lines in India. ![]() in such cases, he bottom portion of the guy wire or stay wire would have no voltage due to insulation of guy strain insulator which normally installed in the middle of the guy or stay wire. Guy or stay or egg insulators give protection in the event of a broken live conductor accidentally energising a guy wire or stay wire and remaining in contact with the live line which does nor trip. Maximum strength is obtained from porcelain of guy insulators by the interlocking of guy cables as the load places the porcelain between the holes in compression Further, the porcelain grooves of these insulators are suitably designed to minimise strans stress. Its rugged design provides relative freedom from breakage due to impact or rough handling. ![]() Rama guy insulators provide high quality insulation for medium and low voltage circuits. ![]()
