A wide variety of conductors can be used for power lines. But, the SIP cable is especially popular https://art-bud-electro.com/kabelno-provodnikovaya/sip that can do the job better. The self-supporting structure is not prone to damage during everyday use. Perfectly withstands the loads created in the open air.
Scope of application of cable products
Sufficiently thick wire can have from two to four strands, each in an individual insulating sheath. Pure aluminum is used as a conductor. It has minimal resistance indicators and is not inclined to oxidize for several decades. But, it cannot be used indoors. The main areas of application can be distinguished:
- Laying overhead lines from pole to pole.
- Installation of individual circuits from a distribution transformer.
- When high-quality short circuit protection is needed.
- Ideal for the industrial environment.
- Laying lines to private houses is allowed.
The wire can be laid from the transformer to the switchboard or meter located on the outside of the building. Laying inside walls, on the outside or in rooms is not allowed. The cable is simply not designed for such everyday use.
Modern design of SIP cable
Modern wire can indeed resist negative operating factors for a long time. Wind, sun rays, significant temperature difference, any kind of precipitation. Even gradual icing and sticking of wet snow will not cause a power outage. All this became possible thanks to the special design of cable products:
- internal metal core;
- several aluminum conductors;
- outer polymeric insulating jacket.
The steel core is the main guarantee that under high loads the cable will remain intact, without any internal breaks or damage to individual aluminum conductors. The conductive part additionally has a twisted structure, which gives it a certain flexibility.
Quality cable products https://art-bud-electro.com/sip-4h25 as insulation uses only polyethylene. It best resists the negative factors of outdoor use. Particularly resistant to cracking from direct sunlight. Does not become brittle in severe frost.
