Quality 66kv Cable Assembly Made Safer For Your Life

May 17,2022

66kv cable is perfect for use as a dielectric material in high voltage transmission lines. Polyethylene is a thermoplastic with outstanding dielectric properties. It has a low dielectric loss factor, which means more power can be transferred through the wire without losing as much energy.

What is 66kv cable?

66KV cable is an abbreviation of cross-linked polyethylene. This has been recognized worldwide as an excellent dielectric material for wires and cables.

66KV xlpe cable is a high voltage, low corona discharge resistant, medium capacity, low loss, the flexible flat conductor made of cross-linked polyethylene (XLPE). The cable is rated for use at 66kv or below and designed for underground burial and direct burial in ducts.

The 66kv cable has a compact conductor geometry with a low profile design which provides flexibility, ease of handling and installation in confined spaces such as tunnels, subways or underground lines. The outer sheath consists of a high-strength non-metallic material that protects against mechanical damage during installation.

66kv cable’s conductor is insulated by a thermoplastic insulation system. The primary insulation is a semi-conducting cross-linked polyethylene (XLPE) with an operating temperature range of -20°C to 85°C. The secondary insulation is a flame retardant cross-linked polyethylene (XLPE) which has been reinforced with glass wool. A PVC outer sheath is applied to the secondary insulation.

The 66kV xlpe cable design has been developed to meet the requirement of high voltage transmission lines, including 132kV and 220kV systems where voltage drop must be kept within acceptable limits.

66kV cable can be used for underground (UG) and aerial (Aerial) construction in dry areas as well as for overhead construction in wet areas. The use of 66kV xlpe cable requires special installation procedures and equipment because of its higher operating temperature range than other medium voltage cables.

Chose right 66kv cable size

The cable size is a very important factor to consider when it comes to the selection of 66kv cable catalogue. The size of a cable refers to the diameter of its conductor, while the cross-sectional area refers to the width and thickness of its conductor. The following are some of the factors that affect the selection of 66kv cable sizes:

Cable voltage

The voltage of a 66kv cable determines its size. For instance, when using a 66kv cable diameter  for high-voltage power transmission lines, its maximum allowable voltage should be above 66 kilovolts (kV). Therefore, for this category of applications, the maximum allowable cross-sectional area will be less than those used for low-voltage power transmission lines or distribution cables.

Conductor temperature

This is another factor that affects the selection of 66kv cables. Conductors carrying current at higher temperatures require larger conductors with the greater cross-sectional area as compared to those used at lower temperatures. This is due to thermal expansion which increases their diameters and hence reduces their cross-sections if they are not allowed enough space for expansion within their insulation covers.

66kv cable price

66kv cable price is based on LME Copper price. Large size will more expensive. For example, 95mm2 cable is more expensive than 70mm2 cable. 5kv cable, 10kv cable, and 20kv cable prices are also different. Please visit our web get a competitive price.

The price of 66kv power cable is calculated according to the following formula:

66KV Cable Price = Copper Price + Base Material Cost + Cable Fabrication Cost + Overhead Costs + Transportation Cost

Copper Price: The copper price is one of the most important factors that affect the price of 66kv power cables. Copper is an essential material for making 66kv power cables, so the higher its price, the higher the cost of 66kv power cables will be.

Base Material Cost: Base material refers to all kinds of materials used in making 66kv power cables such as steel wire, aluminum wire, copper wire, etc., which have a great impact on the production cost of 66kv power cables.

Cable Fabrication Cost: Cable fabrication refers to all kinds of processing techniques used during the production process such as drawing, extrusion, welding, etc., which have a great impact on the production cost of 66kv xlpe cables.

Overhead Costs: Overhead costs include management expenses, office expenses, other staff costs, etc.
