OVM steel entangled the system of guy cable of line has already passed the course of more than ten years since beginning development in 1990. Since the one year, OVM entangle line succeed ground more than ten bridges application at home and abroad already by guy cable system by steel, Obtain more than ten patents altogether, finishes several dozen scientific findings .

Entangle at steels lines guy cableses systems is for kinds of new-type guy cable system,it apply to heavy, in step by the cable-stay bridge and of different types to last structure of choosings of foot-path . OVMs entangle steel solve guy cable anchor careless dependability under low stress state and moved under low stress state insert follow up at line guy cable systemses Situation loose to take off question, take measures from structure and raise steel entangle line resist tired performance by guy cable, OVM 200 and OVM 250 guy cable system resist tired stress one and reaches 200 and 250 MPas respectively. Go on from three major parts antiseptically : Ask for the body and adopt multilevel antiseptic ; The guy cable anchor sets up seal installation , the high pressure pours into the antiseptic oil antiseptically in the device; Office at other anchors together antiseptic head careless units anchor, utilize and protect and cover fill with the antiseptic oil, Airtight to the careless unit of the anchor. OVM entangle line succeed in developing and build and offer one a kind of news train of thought and products for of our country cable-stay bridges by guy cable system by steel.

 OVM steel stranded wire back stay system from 1990 beginning research to manufacture since then, already through more than ten years of process.Since more than ten years, OVM steel stranded wire back stay system already successfully in domestic and internationally more than tenly mount bridge appliance, totally get patent ten remaining item , terminate several item section  fruit.
Steel stranded wire back stay system is a kind new model of back stay system, can appliance in large, midspan diameter of cable stayed bridge and every kind of type of  pick structure.OVM steel stranded wire back stay system settle back stay at low stress status cast anchor  firm sum under lowly the stress the status is action by the dynamic load clip sheet of little tailgate with under specially the condition of loose subject, from the structure take steps, stilted steel stranded wire back stay of antienzyme fatigue performance, OVM200 sum OVM250 back stay system antienzyme fatigue stress amplitude respectively hit 200 sum 250 MPa.Rot proof from three bulk analysis steer:Cord corpus adoption polypeptide lay rot proof structure(4~6 lay) and first in of aseptic technic sum industrial art;Back stay anchor setup have air tight seal apparatus, apparatus inside high barometric maxima potting rot proof olein rot proof;Anchor  unit of rot proof is together with exoenzyme anchor head together rot proof, take advantage of safeguard hood inside the  fill with rot proof olein, vs anchor  unit air tight seal.OVM steel stranded wire back stay system of triturate win, for our country cable stayed bridge construction tender a kind new way of thinking sum product.

  Steel stranded wire back stay system have flws merit:
(1) antienzyme fatigue performance higher -.
(2) fair foreign land construction performance.
(3) economies.
(4) fair protecting performance.

The steel entangles the system of guy cable of line has the following merits: (1)It is high to resist fatigue performance. (2)Good strange land construction performance . (3)Economic. (4)Good shelter performance .
