As the main
carrier of power transmission, cable is widely utilized in electrical gear,
lighting circuit, household appliances and so on. The quality from the cable is
directly affect the engineering high quality, and the security of life and home
of customer. There are lots of Cable Manufacturers in the market, and there are also numerous
varieties of cable. You need to select proper cable according to the use of electrical
energy load. You are able to discover associated models and specifications in
the cable specification.
Generally,
whenever you choose a wire and cable, except electrical wire size and
electrical wire price, you need to also notice some particulars as below.
First of all, you
need to select right wire and cable types. At this time, you should think about
the objective, the laying conditions and safety, for example: based on the
various utilizes, you can choose energy cable, aerial insulated cable and
manage cable; according to the different laying conditions, you are able to
choose common plastic insulated cable, Screened Manage Cable, steel tape
armoured cable, Armoured Power Cable, anti-corrosion cable and so on; based on the
safety requirements, you are able to select the flame retardant cable, halogen
free flame retardant cable, fire cable, etc..
Secondly, the
option from the standard of wire and cable. Whenever you need to ensure the
specification of wire and cable, generally, you should consider heating,
voltage loss, economic present density, mechanical strength and so on.
Based on the
encounter, for the low-voltage energy line, due to its larger load present, you
should consider the section first according to the conditions from the heating,
and then verify the voltage loss and mechanical strength. For low voltage
lighting line, it has a high specifications around the voltage level, you
should choose the section according to the permissive voltage loss situation,
then checking the heating conditions and mechanical strength. For high voltage
transmission lines, firstly, you need to choose section based on financial
current density, and then check the heating circumstances and allow voltage
loss. For higher voltage overhead line, expect the section, heating conditions,
you also ought to consider its mechanical strength. If the user has no
experience, some professional units or individuals will offer some ideas for
you personally.
Finally, you need
to choose the Cable
Manufacturer. There are lots
of variations between the different products supplied by various Cable Manufacturer even they've exactly the same name or same
size. The inner material is very important for a cable. A good cable, it adopt
great copper or some other high conductivity metal, but you cannot verify it by
yourself, so you need to choose a Cable Manufacturer who has a high inspection regular and high
quality requirement.
