Medium Voltage

Supplier Kabel Jakarta memberikan informasi apa itu Medium Voltage Cable atau disingkat MV di sekitar terminologi kelistrikan. Tentunya pembaca dapat melihat ulang dengan tulisan rating voltage yang sudah ditulis sebelumnya di sini. 

Kabel tegangan menengah ini umumnya menggunakan JAKET LUAR : XLPE atau Cross Linked Poly Ethylene. XLPE adalah jenis jaket yang lebih kuat dari PVC dari segi ketahanan suhu. PVC dapat menahan suhu sampai dengan 70' Celcius, namun XLPE dapat menahan sampai dengan 90 ' Celcius.

XLPE digunakan umumnya

• Tempat ruangan panas

• Ruangan beresiko tinggi atau berpotensi "Environment Stress Crack" 

Mengacu pada brosur kabel SUPREME Medium Voltage, berikut ini sedikit gambaran tertulis Komponen apa saja yang digunakan pada desain kabelnya:

MV CABLE CONSTRUCTION

Medium voltage “SUPREME” cables are designed based on IEC 60502-2, SNI, SPLN

43-5 or others international standards upon request.

• CONDUCTOR

 The conductor made from annealed copper wire, circular stranded com

 pacted or round segmental compacted according to IEC 60228, BS 6360,

 AS 1125 or SPLN41-1.

• CONDUCTOR SCREEN

 The conductor screen made from extruded semi conductive compound.

• INSULATION

 The conductor screen are covered with an extruded layer of XLPE

 compound according to IEC 60502, AS 1429-1, BS 5464 or SPLN 41-9.

• INSULATION SCREEN

 The insulation screen made from extruded semiconductive compound in

 combination with the metallic screen. The metallic screen consist of

 a layer of either copper tape or copper wires with copper tape binder.

Conductor screen, insulaton and insulation screen are produced by triple

extrusion with N2 gas dry curing.

• BEDDING/FILLER

 The bedding and/or filler made from an layer of exruded PVC or

 non-hygroscopic material which compatible with the insulation and

 operating temperature of the cable.

• METALLIC SHEATH

 The metallic sheath made from lead alloy material with kinds of grade

 such as 1/2 C, E grade. The main function of lead sheath is to

 protect the cable from physical deterioration caused by chemical liquid

 such as sulfides , waste oil and to provide an impermeable water barrier.

• INNER SHEATH

 The inner sheath made from a layer of extruded PVC ST2 type to IEC

 60502-2 or YM/2 type to SPLN 41-2 , type 9 to BS 7655 or other

 international standards.

• ARMOURING

 The armouring made from either welded continuously aluminium

 corrugated, galvanized round steel wire, double galvanized steel tape, round

 aluminium wire or double aluminium tape.

• OUTER SHEATH

 The outer sheath made from a layer of extruded Polyethylene or PVC ST2

 type to IEC 60502-2 or YM/2 type to SPLN 41-2 , type 9 to BS 7655 or

 other international standards.
