Bayyana Takardukan Dukkantuka

Akawo da suka fi yawa a cikin dukkantuka da za su iya tabbatar da su a cikin bayyana. Dukkantuka na gaba yana da

• Conductor

• Insulation

• LAY for Multicore cables only

• Bedding

• Beading/Armouring (if required)

• Outer Sheath

Conductor

Conductors suna da ƙarfi mai yawa wajen gudanar da dukkantuka a cikin dukkantuka. Conductors suna da ƙarfin da dama. A cikin ƙasashen dukkantuka, ana amfani da copper (ATC, ABC) da aluminum conductors don dukkantuka. Akwai nau'o'i da dama da conductor Class 1: solid, Class 2 stranded, Class 5 flexible, Class 6 Extra flexible (Mostly used for cords and welding), etc. Conductor sizes suna da ƙarfin resistance.

Insulation

An sa PVC (Poly Vinyl Chloride), XLPE (Crosslinked Polyethylene), RUBBER (Various Types of Rubber) don insulation provided on each conductor of a cable. Insulating material yana da ƙarfin operating temperature.

Cha4

Cores suna da color-coding don in ƙarfafa su don in amfani da colors da dama a insulation ko number printing a cores

Beading (Inner Sheath)

Wani baki na dukkantuka wannan shine inner sheath. Ana amfani da ita a Multi-core cables. Ita ce take ƙarfafa insulated conductors together a multi-core power cables da kuma provides bedding to armor/braid. Wani baki na dukkantuka yana da PVC (PVC ST-1, PVC ST-2), RUBBER (CSP SE-3, CSP SE-4, and PCP SE-3, PCP SE-4, HOFR SE-3 HOFR SE-4, HD HOFR SE-3 ETC).

Armoring

Akawo da suka fi yawa suna da G.I. WIRE ARMOURING, G.I. STEEL STRIP armoring. An yi ita tare da G.I. WIREs, GI, or STEEL STRIPs one by one a inner sheath. Armoring yana da ƙarfin wajen ƙarfafa earthing shield to the current-carrying conductors as well as it is also used for earthing purposes of the cable for safety.

Idan an yi faɗa a insulation a conductor, fault current gets enough paths to flow through the armor if it is properly earthed. Providing extra mechanical protection and strength to cable is an important added advantage of armoring. A mining cables an yi ita don conductance.

Beading

ANNEALED TINNED COPPER WIRE, NYLON BRAID, COTTON BRAID suna da ƙarfin wajen yi ita. Braiding yana da ƙarfin wajen ƙarfafa high mechanical protection to cable and also used for earthing purpose. The significance of braiding is it is more flexible in comparison to armoring.

Outer Sheath

Wannan shine outermost cover of the cable normally made of PVC (Poly Vinyl Chloride), RUBBER (Various Types of Rubber), and often the same material as the bedding. It is provided over the armor for overall mechanical, weather, chemical, and electrical protection. The outer sheath is the protection offered to the cable not much electrically but more mechanically.

Mainly above 6 square mm cables are called power cables but it depends upon the use of a cable. For PVC power cables we use IS:1554 and for XLPE power cables we use IS:7098 and for Rubber-based power cables, we use IS:9968 and other relevant specifications. Power cables are defined by voltage grade and nominal cross-sectional area.
