Paradise Cables Limited (PCL), established in year 1989 and now one of the leading

manufacturers of cables and conductors in the country, is a corporate unit of Paradise Group of

Industries, located at Fatullah, Narayanganj. The PCL product range includes PVC/XLPE insulated

and sheathed, armoured/unarmoured wires and cables, overhead conductors and cables. (fordetailed product range please refer to list at the end of this catalogue).

The PCL plant is equipped with most modern world class cable manufacturing machinery having

latest electronic microprocessor based controls and automations to manufacture all types of

quality cables and conductors inconformity with latest versions of International standard e.g.

German standards (VDE 0271 & 0250), British standards (BS 6004) etc. In addition PCL

manufactures XLPE insulated cables with screen/without screen and unarmoured/ armoured as

per IEC 60502 up to 33kV system voltage.

The copper and aluminium wire required for manufacture are cables is drawn from the wire rods

produced by Paradise Metallurgical Complex Limited (PMCL), also a Paradise Group company.

The PMCL uses highly refined copper cathodes and Aluminium ingots with high degree of purity

having metal content better than 99.99 % to produce wire rods of conductivity better than the

specified requirements of international standards.

The PVC (Poly Vinyl Chloride) / XLPE (Cross Linked Polyethylene) cable insulations are now well

known for their excellent electrical and mechanical properties as well as good chemical

resistance. PVC/XLPE cables are simple to handle and easier to make joints. XLPE insulated cables

have maximum operating conductor temperature of 90o

C, whereas PVC insulated cables have

maximum operating conductor temperature of 70o

C. PVC compounds are manufactured in

house by PCL by using world class PVC resins, stabilizers, plasticizers and other chemicals

required to obtain desired properties of PVC compounds as per the relevant international

standards. XLPE compounds are imported from reputed manufacturers.

PCL follows a very strict quality control system. The quality checks start from the receipt of rawmaterials, in-process checks & tests and finished cables. The PCL laboratory is equipped with

latest test equipments to carryout all the necessary tests as per national and International

standard specifications. Each length of cable manufactured is subjected to the tests as per the

relevant International standards. The experienced and technically qualified cable testing

engineers ensure that all the cables leaving the PCL factory meet all the necessary requirements

of the relevant standard.

All cables produced by PCL are marketed with engraved brand name "Paradise Cables

Bangladesh" at an interval of every meter or less.

The continuous quality Assurance System followed by us guarantees the quality of our product,

as a result we received ISO 9002 accreditation in early 1998 and reconfirmed subsequently to the

latest version ISO 9001:2000 certification.

Most important component / raw material in cable manufacture is the conductor insulation. The

performance and properties of cables mainly depend upon the conductor insulating materials. In

the modern cable manufacture the most commonly used materials are PVC, Polyethylene (PE),

Rubber etc. Polyethylene is the most superior in all the insulating materials due to its highinsulation resistance and low dielectric constant. However it lacks in mechanical and thermal

properties. By cross-linking these properties are improved. Cross-linked Polyethylene or XLPE as it

is commonly referred to, is the most superior insulation.

XLPE for cable insulation: PARADISE uses the world famous Sioplas technology for

manufacture of XLPE cables. Polyethylene is a polymer of Hydrogen and Carbon atoms, which

form a long flexible chain. These chains are independent and therefore are loosely connected.

By the process of chemical cross-linking, these chains are linked to form a strong mechanical

bond. The XLPE compound possesses improved mechanical properties without loosing or

degrading the superior electrical properties of PE. XLPE compound is applied by extrusion and is

then cured to cross-link.

Properties of XLPE compound :

Thermal Properties: After cross-linking the thermal resistance of the PE material increases and it

remains stable at higher temperatures. As compared to PVC insulated cable, which is rated for

max. 700

C operation, the XLPE is rated at max. 900

C operation. The low temperature withstand

capacity of XLPE is -400

C as against -150

C for PVC. Due to higher cable operating temperatures

the XLPE insulated cable can carry 20-25% higher current than PVC insulated cable. The thermal

ageing properties are excellent and cables insulated with XLPE have longer life span.

Electrical properties: XLPE offers higher insulation resistance, typically 100 times better than

PVC. The dielectric constant, which is responsible for electrical losses in the cables is less than

half of that of PVC. Therefore the performance of XLPE insulated cables is better, especially for

HT cables.

Mechanical properties: XLPE is mechanically more stronger than PVC, due to cross-linking. It

has better abrasion resistance as compared to PE.

Chemical Resistance: XLPE resists many chemicals, acids, oils and greases.

FRLS properties: The XLPE compound does not contain chlorides, as in the case of PVC,

therefore do not emit harmful Halogen gasses during fire condition. The smoke generation is

also very as compared to PVC. The XLPE is thermosetting compound and therefore cable retains

its electrical integrity for longer duration under fire. The FRLS properties of XLPE are far better

than PVC.

Armour is optional Paradise offers armouring by Round wires or Flat wires or Double tapes. The

material of armour for Single core is aluminium whereas, for multi-core cables it is Galvanized

Steel. Counter helix of Galvanized steel tape is provided on request for round steel wire & Flat

wire armoured cables. The armour is applied over the inner covering as per IEC 60502-2.
