Company APERVID, as an independent enterprise, was founded in May 2010 for development and production of materials and equipment for energetics and telecommunications. So far as in our product range utility rope, that can be used during laying the wires, ground wires and aerial bundled cable, wasn't and still isn't on the last place. Thus, in 2011 was made a decision of organizing of our own production of utility rope.
Firstly, we considered production of steel non-woven rope. However, we it had several disadvantages: large weight per meter, impossibility of using it on non-disconnectable power lines, large amount of intersection of industrial facilities and etc. Thus, our attention was drawn to synthetic materials. As a result of studying different types of materials and visiting enterprises, ultra high molecular weight polyethylene Dyneema® (UHMWPE, product of DSM-Netherlands) was seemed to be the most suitable material.
In manufacturing process we use only original fiber Dyneema®, made in Netherlands.
Dyneema® fiber posesses following important advantages:
- High specific strength, that is comparable to wire ropes;
- Stretching start only at max. loading;
- Hydrophobic;
- UV resistant;
- Low weight;
- Wear resistant;
In 2012 termless contract with producer of fiber, subdivision of netherlander concern DSM - DSM Fiber Solutions, was signed.
For manufacturing of such an important ware as utility rope it was necessary to have reliable and quality equipment. So, we chose the world's leading manufacturer of braiding machines - Herzog (Germany). First Herzog braiding machine was bought and installed in 2012.
Reception of the first braiding machine, Germany, 2012
In the end of 2012 first prototypes of utility rope made from Dyneema® were released. Technology improvement and development was carried out in cooperation with specialists from DSM laboratories, where we tested first prototypes of our APERVID ropes.
In order to improve rope's abrasion resistance we installed special coating and drying equipment where, as coating material, we use specific multicomponent polyurethane.
From 2016 we have been producing rope from aramid fiber, Kevlar® (DuPont, USA).
Nowadays our product - braided rope with diameter from 1 up to 60 mm made from UHMWPE (Dyneema®), Aramid (Kevlar®), Polyester for builders, power engineers, operators, outdoor enthusiasts (we produce ropes-winches for jeeps and ATV, and also shackles), oilmans and yachtmen.
Besides rope, company APERVID owns several patents and delivers underground cameras for stocking cables, radio makers, combined wires, robot for hanging utility rope on transmission line support (APERVID200), reusable basement for power lines 6-10 and etc.
