PVC Unarmoured Cables
Power cables for energy supply are installed outdoors, in underground, in water, indoors, in cable ducts, power stations, for industry and distribution boards as well as in subscriber networks, where mechanical damages are not to be expected.

Standard length cable packing:
Coils 100, 200, 300, 500, 1000 m. in wooden reels

 

1>. Power Cables (Armoured / Unarmoured – PVC / XLPE)

Hongda Cable manufactures a wide range of Armoured Cables, Armoured Power Cables, Armoured Electrical Cables, PVC Armoured Cables and XLPE Armoured Cables. XLPE means cross-linked polyethylene or vulcanized polyethylene. The basic material is low density polyethylene. Polyethylene is a thermoplastic material consisting of long chain of hydrocarbon molecules. At elevated temperatures these molecules tend to move relative to one another so that the material becomes increasingly deformable and will eventually melt at the temperature around 110°C.

By means of process similar to the vulcanization of rubber the polyethylene molecules can be cross-linked. The process of cross-linking or vulcanization consists of producing chemical bonds at interval between the long molecular chain to give a “ladder” effect which prevents slippage between molecules as a result of cross-linking the material becomes heat resistant and does not soften at higher temperatures. Further it has better resistance to stress cracking and good resistance to ageing in hot air. With the change of structure there is no adverse effect on electrical properties.

 

Advantage of “HONGDA CABLE” XLPE Cables

• Dielectric losses are very small
• Higher current carrying capacity
• Higher short circuit rating 250°C as against 160°C for PVC
• “HONGDA CABLE” XLPE can retain flexibility down upto – 40°C
• Jointing and Termination is easy
• Light in weight
• They are not prone to fatigue damages due to vibrations or loading cycles
• Has better resistance to most chemicals, oils, acids, etc
• Can be installed along cable routes without elevation limitations

2>. Control Cables (Armoured / Unarmoured – PVC / XLPE)

A wide range of Control Cables (PVC Insulated & Sheathed Flexible Cables) are available with us. These control cables have high tensile strength and accurate resistance to high temperatures. These cables work in both dry and moist conditions. We offer them in black/gray core colours and gray, black and white sheer colours. They are highly flexible for application in different electrical environment. These control cables used in tool machines, steel production units, electrical substations etc.
