Low voltage wire specifications

Low voltage cable and wire come with different sizes, material, and specifications. Low-voltage cables are made of rigid, solid or twisted copper and aluminum conductors and flexible (bare or tinned) copper conductors. XLPE, PVC, LSF/LSOH and elastomeric compounds are the primary insulating and protective compounds for these types of cables. Steel wire or steel tape (or aluminum for single conductor cables) can be applied under the outer jacket for additional mechanical protection. Halogen-free, fireproof, fireproof and low-smoke emission cables for special applications are also available. They are aluminum or copper cables that are insulated with various polymers and have a voltage tolerance of 300 to 3000 volts. Low voltage cables are suitable for power transmission in electric motors. Low-voltage cables are divided into the following categories according to conductor type:

  • Multicore wire
  • Insulated wire
  • Rebar or single core wire

Low voltage cables are generally resistant to hydrocarbons and petroleum substances, are fire and fire resistant and produce little smoke when burned. Low voltage cable functions

  • Cables can have different layers of insulation, including PVC

This insulation is mostly used for low voltage cables and has the following properties:

  • Non-flammable
  • Cheap
  • Flexible
  • Low voltage cables are 1000 volts or less.

Meaning of letters used in low voltage cables The structure of low-voltage cables is indicated by letters, the first letter indicates the type of conductor (N copper and NS aluminum), and the second letter indicates the type of insulation (U plastic and G rubber). The letters that determine the type of jacket are; Y: Plastic K: KL Series: Aluminum The letters that determine the armor type are; B: Steel, Gb: Galvanized steel The letters to determine the low voltage cable are: NYY: Hess conductor insulated plastic sheathed cable NAYY: Aluminum conductor insulated plastic sheathed cable NGG: Copper conductor insulated rubber sheathed cable NAGG: Aluminum conductor insulated cable, insulated rubber sheathed NYKB: Copper core Plastic in lead sheathed steel armored cable NYYGb: Copper core insulated plastic sheathed galvanized steel armored cable NKBA: copper core paper insulated lead sheathed steel armored cable and plant fiber sheath.

Low voltage cable specifications

One important factor which can change the specifications of low voltage wire and cable is the sheath. The quality of the insulation you use plays an important role in successful operation. Therefore, it is crucial to choose the right insulation material for the cables. Here are the properties to look for: Properties of insulating materials

  • Low line loss due to high insulation resistance.
  • High dielectric strength prevents cable collapse.
  • Excellent mechanical strength to withstand industrial line processing.
  • It should be non-hygroscopic, meaning it should not absorb moisture from the air or soil.
  • Non-flammable.

XLPE Polyethylene plastic is very suitable for the production of hydraulic pipes. The shape memory properties of XLPE are due to its 3D molecular bonding structure. In short, low voltage XLPE cables are essential in industries where wires and cables are exposed to:

  • extreme heat conditions
  • Electrical applications involving high voltage
  • Stress and fatigue
  • liquids such as water
  • Hazardous chemicals
  • Plumbing, mining and numerous electrical applications can all benefit from XLPE cables. XLPE cables are also used in the chemical and commercial and residential heating industries.

PVC (polyvinyl chloride) The insulating material is made of synthetic material. It is made using acetylene polymerization. The insulating material is made of synthetic material. It is made with white powder. This insulating material is mixed with a high-boiling liquid plasticizer, making it suitable for low-voltage wire insulation. It has a high temperature range. Plasticizers turn substances into jelly and make them plastic. PVC has excellent insulation resistance, good dielectric strength and mechanical durability over a wide temperature range. It is oxygen-inert and almost inert to several bases and acids. PVC insulated cables are commonly used in low voltage lighting cables for household lamps and electrical installations due to their mechanical properties. (ie elasticity). The difference between XLPE and PVC The main difference between XLPE and PVC is that XLPE can be used in both high and low voltage applications. Its construction resists abrasion, stress,s and other forms of wear and tear. Because PVC insulation cannot withstand that much stress, it is only suitable for low-voltage applications. Other notable differences are:

  • XLPE insulation has a longer life expectancy for low voltage cables than PVC insulation.
  • Cross-linked polyethylene is more environmentally friendly because it does not contain chlorides.
  • XLPE can withstand high temperatures through insulating materials.
  • Cross-linked polyethylene provides higher moisture resistance.

I know you're thinking about it; why do you need a test cable? Cable testing is necessary to reduce test time. This is done to ensure:

  • Cable consistency
  • Wire quality
  • function of the cable

You may have had a cable fault and after a while it became a problem. Visual inspection of all electrical wiring in your facility is an excellent way to detect problems before they cause downtime. Check cables for copper corrosion, split insulation, moisture on wires and various other signs of cable deterioration. Insulation thickness The insulation resistance (IR) test measures the total resistance between any two locations separated by electrical insulation. Therefore, this test determines the effectiveness of the dielectric (insulation) in resisting current. Such tests are essential to determine the insulation quality of a product. Perform regular tests to detect potential insulation problems and avoid user error or costly product repairs. Sheath thickness Sheath resistance testing is an important field diagnostic procedure to detect potential cable faults. It is worth noting that the purpose of this exercise is to demonstrate the integrity of the cable jacket; the outer sheath is used to shield the final cable from the surrounding environment. So the label "shed resistance test" is a bit misleading. Network Rail routinely uses the sheath resistance test to maintain the sheath integrity of its graphite-coated underground NR/PS/ELP/00008 low-voltage heating cables. The graphite coating acts as a semi-conductive layer through which a potential current can be passed for a predetermined length to perform the test.
