SIP, the self-supporting insulated wires, are used to transmit electrical energy in the overhead power and lighting networks at an alternating voltage of 0.6\/1.0 kV with a frequency of 50 Hz. They are also used for branching from the trunk lines to the enter to residential buildings and utility buildings. The laying is carried out on supports, along the walls and structural elements of industrial and residential buildings.
\nSIP wires are easy to lay, they keep their shape well, do not sag under their own weight and do not require additional armouring. They are made from eco friendly materials and do not emit harmful substances into the surrounding nature.
\nThere are several types of SIP, they differ in design features and insulating material. A common feature is the insulation on the phase conductors. And the neutral carrier wire can be insulated, made without an insulating coating, or be absent at all.
\n\u00a0The design of the wires is the aluminum insulated conductors of the same cross-section stranded into a bundle (tables A.1, A.2 of the National Standards of Ukraine 4743:2007). The conductors are always aluminum and never copper. The phase conductors can also be made of an aluminum alloy, and the neutral conductor consists of a steel core and an aluminum sheath. The electrical insulation of the conductors is made of cross-linked light-stabilized polyethylene or thermoplastic light-stabilized polyethylene.
\nIn the regions with increased intensity of ultraviolet radiation, it is advisable to use wires with insulation of light-stabilized polyethylene, resistant to ultraviolet radiation and ozone. In places with a high probability of significant external heating of the wire during operation, use wires marked \u00abn\u00bb and \u00abng\u00bb, the insulation of which is made of non-combustible self-extinguishing materials. And in conditions of sudden temperature changes, adhesion of snow, icing and a similar environment, you should choose wires with thermoplastic insulation.<\/p>\n","protected":false},"author":1,"featured_media":7729,"parent":4788,"menu_order":4,"comment_status":"closed","ping_status":"closed","template":"template-page-product.php","meta":{"inline_featured_image":false},"yoast_head":"\n
