Four Core System Since the 1970’s the Four Core System has been adapted in many Central and North European countries e.g. in Austria, Germany, Ireland, United Kingdom, Poland, Hungary, Russia and Scandinavia. The four insulated conductors that share the tensile load equally, have a size range of 16 to 185 mm2. They are made of aluminum with a relatively high tensile strength. Therefore, the breaking load of the cable is relatively high, as well. Insulation of the cores is typically made of XLPE or PE. The cable can be supplied with one or two insulated conductors for street lighting. Read more...

Insulated Messenger Wire System (IMWS) An insulated messenger wire cable consists of one to five black, weather resistant, high density or cross-linked, polyethylene insulated conductors twisted around an insulated aluminum alloy messenger (typical tensile strength 300 N/mm2). The Ensto portfolio for Insulated Messenger Wire System, Ensto IMWS, includes connectors, tension and suspension clamps, pole fuse switches and various pole support and earthing accessories. Our competitiveness is based on longterm customer relations resulting in safe systems for the most demanding circumstances using durable...

Uninsulated Messenger Wire System (AMKA) Ensto has developed solutions and integrated product packages for various Low Voltage ABC (Aerial Bundled Cable) systems since the early 1960’s. The solutions are designed to meet the international and local standards and take into account the special requirements of the urban, rural and forested areas, density of population, climatic conditions, available investments etc. The AMKA System is a reliable, safe and easy way to build a low voltage overhead line system. Because of the small amount of components and short poles it is easy to build and preferred...

Copper Bars Copper bars are used together with busbar connectors to connect Cu- or Al- conductors to highor low-voltage transformer bushings. It is important to brush and grease the Al-connection. Flat copper bars are tin-plated to reduce corrosion between aluminium and copper. The copper bars and connectors are delivered separately. Read more about Copper Bars on page 31. Bird Protectors Environmental aspects are increasingly important when building an electricity network today. Ensto is working together with electricity utilities and environmental experts to find ways to protect wildlife from...

Fixing Materials for Pole and Wall Mount AB cables have usually a single layer of insulation only. They are not intended to be installed directly to the supporting surface. The wall mount fittings and the distance clips make it possible to install cables on various surfaces horizontally and vertically. Read more on pages 40-42. Suspension Hooks AB cables are suspended on wooden, concrete or steel poles and walls. Every support requires its own tensioning device. The Ensto hook program has a solution for all needs and tensions required. The installation is easy and quick and no special tools are...
