4. Products covered (HS or CCCN where applicable, otherwise national tariff 
heading. ICS numbers may be provided in addition, where applicable):  
HS: 8536.7000 These requirements cover the shielded and non -shielded medium -voltage 
power cables including single and multiple conductors. Cables have one or more stranded 
copper or aluminum conductors that are insulated with a solid, extruded dielectric. Cables 
that have a metal sheath or interlocked armor incorporate an e ffective grounding path. A 
grounding conductor is optional in other cables. Cables for direct burial are so marked 
and have an overall covering (see 1.4 for direct -burial cables that are not covered). Cables 
that are for use in cable trays generally are so  marked (see 62.1 and 62.2). Cables that 
are sunlight -resistant generally are so marked (see 64.1 – 64.3). Cables that are marked 
"MV-90" or "MV -90 dry" have a maximum operating temperature of 90°C (194°F). Cables 
that are marked "MV -105" have a maximum op erating temperature of 105°C (221°F) for 
use where design conditions require a maximum conductor temperature above 90°C 
(194°F). Cables that are marked "dry" have insulation for use only in dry locations. All 
other cables have insulation that is for use in  both wet and dry locations. Multiple -
conductor cables that include one or more optical -fiber members are surface marked to 
so indicate. Cables that are marked "oil resistant II" are for exposure to mineral oil at 
temperatures not in excess of 75°C (167°F) . Cables that are marked "oil resistant I" are 
for exposure to mineral oil at temperatures not in excess of 60°C (140°F). A multiple -
conductor Type MV cable that has a smooth (other than lead) or corrugated metal sheath 
or that has interlocked metal armor may be marked for use also as Type MC cable; 
Electrical apparatus for switching or protecting electrical circuits, or for making 
connections to or in electrical circuits (for example, switches, relays, fuses, surge 
suppressors, plugs, sockets, lamp -holders , junction boxes), for a voltage not exceeding 
1,000 volts (HS 8536)  
5. Title, number of pages and language(s) of the notified document:  Medium -Voltage

  6. Description of content:  Requirements for Medium -Voltage Power Cables including 
requirements forconstruction, performance and markings.  
7. Objective and rationale, including the  nature of urgent problems where 
applicable:  In recent times large quantities of faulty components has been entering the 
country. The risk of electrocution and fire is high. Hence the need to exclude components 
that do not meet the requirements of the stan dards.; Protection of human health or safety
