Roller forming double twist strander

The speed of tight type stranded wire can reach 200m/min

Rolled forming type of stranded wire is a combination of rolled forming and bundle stranded wire two highly efficient production process, to create the domestic a high speed of continuous production unit.

 

Rolled forming type bundle twisting process is a combination of rolled forming and double twisting two advantages of production technology.Integrate the two systems, created the high speed continuous manufacturing unit. It can product 300mm tight type conductor under the speed of exceeding 200m/min. The equipment not only can under the high-speed production of tight type conductor, and from wire drawing to extrusion entire process can save a lot cost.

This is a technical solution in the tight type conductor manufacturing process, it can save large costs in process of wire drawing to cabling to extrusion etc. Because rolled forming stranded wire can use single core, it has cost saving and the following features:

High stranded wire capacity (Average daily production of 40 tons of tight aluminium conductor)

The larger wire drawing capacity

The fewer wire drawing waste product quantity

The fewer sheath cost

Less investment

Increase ROI

Short setup time of machine

Less semi-finished product in process of production

Short working time

Small core wire storage area

Save 75% energy compare with general frame twisting machine

Rolled forming wire twisting machine of superior performance to let you don’t reduce finished product can save a lot cost. To recognize the advantages and other new technology and new specifications, these will promote the development of the stranded wire design, will also dig further optimize the stranded conductor manufacturing capacity.

Profile

Rolled forming wire twisting machine according to the design can meet the take-up bobbin up to 1250mm-1600mm-1800mm-2000mm-2240mm-

2500mm. Can production products including:

Copper, aluminum twisting conductor from 16 to 40mm

Can produce bundle conductor, tight type twisting conductor, the filling rate is 76% to 97%

Steel-core aluminum stranded wire

Full aluminium conductor, full aluminium alloy conductor

Insulated conductor cabling

A kind of “outer/inner” design, there is twisting bow, traction, take-up, cycloid, loading and unloading platform.

Based on the stranded wire design, rolled forming stranded wire can reach 4 layers. Each roller drive alone, can change the roller speed accurately,in order to make up for the difference of screw length, also can be more accurate allocation each layer of conductor tension, optimize eventually conductor straight degree.

The machine for lateral loading and unloading, equipped with standard ground loader, can be minimal manpower loading and unloading take-up bobbin.

Single core wire

Single conductor diameter represents a stranded wire design method and production methods, can effectively reduce from the pole to stranded wire cost and does not harm the performance of the conductor.

Traditional stranded wire way is to use different diameter conductor, and the SIW this concept is to use the same diameter of the wire to realize many kinds of cross section.

Single conductor diameter accord with standard of main conductor in the world. Handing rolled forming twisting machine is the only make full use of the advantages of single conductor devices.By using a single core wires on stranded wire design, can be more effective resources saving.

Large wire drawing capacity

Few wire drawing waste

Low insulation cost

High ROI

Fast production setup

Small production workload

Short circulate time

Small inlet storage area

The highest of capacity in twisting equipment

Rolled forming system

Rolled forming wire twisting machine is equipped with a single rolled forming system. The purpose of taking the wire twisting material to make theoptimal shape according to the design of stranded wire structure.

Rolled system can be simple two layer (such as: 1+6) or complex four layers (such as: 1+6+12+18+24) structure. The stranded wire design decisionsystem of configuration.

Multiple design schemes

Inlet wire rolled forming, take a layer of each conductor rolled forming by the roller.

Round conductor made from multi-round conductor surround. Example is the “S” shape rolled forming system.

Pay-off

Column type pay-off or static coiling cable can accommodate aluminum 1000kg (2000Ib) or copper 3000kg (6000 Ib) located behind the strandedwire. Column type pay-off can continuous operation, it’s the preferred solution of single core wire way.

Handing rolled forming bundling machine, owned patent of rolled forming system. Production tight type conductor compared with the traditional way, its owned the greatest production capacity.
