The specification of 66KV wire and cable with the xlpe insulation made it usable in submarine conditions. XLPE cables are insulated with XLPE, a material that is becoming more popular due to the distinctive physical and chemical qualities it possesses. These cables have good qualities that make them suitable for a variety of applications in any environment due to the cruciform structure of the polyethylene molecules that make up the cables. For instance, these cables have the ability to handle voltage classes ranging from 600 V to 130 kV. As a consequence of this, they manufacture XLPE cables in high, medium, and low voltage varieties. In the following paragraphs, we will investigate this type of cable and discover how XLPE cables may be used to connect our electrical equipment so that we can get the maximum amount of power. A cable that has insulation or a sheath that is composed of cross-linked polyethylene (XLPE) is referred to as an XLPE cable. The covering that is wrapped around the conductors on the inside of the cable is referred to as insulation. Nevertheless, the coating is the most protective layer for the cable, and both the coating and the cable itself must be able to prevent the flow of electricity. Insulating materials for these cables are often made of cross-linked polyethylene, which has a molecular dielectric structure that is cross-linked rather than linearly polarized. These cables are typically utilized in high-voltage applications. The word XLPE may be broken down into two parts: the first two letters stand for the same structure, while the last two letters stand for polyethylene. Because of the ionic crossover structure, the cable is more flexible and resistant to mechanical stress, moisture, corrosion, and heat. It also has increased resistance to these factors. The ductwork in buildings that have a high relative humidity is one of the most typical applications for XLPE cables. The following elements make up this particular variety of cable: Conductor: The term "conductor" refers to the central core of a cable that is responsible for transferring electrical current. 
Copper and aluminum are both examples of common materials that are used in the production of conductors. The voltage rating of 600 volts is considered to be appropriate for this kind of cable. Semiconductor layers: These layers, which are also referred to as "semiconductor layers," are utilized to cancel out and uniformly distribute the electric field. Insulation: There is a layer of insulation around the conductor to prevent current from leaking into the cable. The insulation is composed of XLPE material in this type of cable. The term "filler" refers to the material that is located inside the cable and is responsible for filling the spaces that are present between the inner insulation, the conductors, and the outer sheath. Outer sheath or jacket: PVC is the outermost part of the cable; it is responsible for insulating the cable and preventing current leakage, which can take place if the inner insulation is torn. Copper conductors are sandwiched between layers of XLPE thermosetting insulation in the cable that goes by the designation USE-2, which stands for Underground Service Entry. Because thermostats can tolerate a certain amount of tolerance, these cables can be utilized in underground applications such as buried cables; they exhibit good resilience to thermal and mechanical stress as a result of the thermostat's tolerance. On the other hand, due to the cable's great resistance to heat, moisture, and sunshine, it is suitable for use in industrial applications such as the power supply of manufacturing machinery. The voltage rating of 600 volts is considered to be appropriate for this kind of cable. RHW-2: The letters "R," "H," and "W" in the name of this insulator are abbreviations for XLPE body rubber insulators, which are resistant to temperatures higher than 75 degrees Celsius and water ingress. 
This insulator is also known as a RHW-2. The rubber or neoprene that is used to make this cross-linked polyethylene gives it a high level of resistance to moisture. The fact that these cables have a number 2 in their names suggests that they are able to tolerate temperatures of up to 90 degrees Celsius. The same is true of the USE-2 cables. This cable can be buried in either dry or wet soil, depending on how well it handles either of those conditions. This type of XLPE cable has a voltage rating of 600 volts and is suitable for use in power systems as well as regular wiring applications. RHH: The first letter of this cable's designation, which is used to define the material it is made of, is "rubber insulation." Similar to the two varieties that came before it, this model is an XLPE cable that operates at low voltage and supports voltages of up to 600 volts. It has a good temperature resistance at temperatures above 90 degrees. Although there are two "h"s in a row in the model name, this cable is not waterproof. However, the high temperature resistance is indicated by those letters. Cables of this sort, such as RHW-2, are utilized for power transmission in manufacturing facilities as well as electrical installations. Additionally, these cables are utilized for general purposes such as switchboards; however, environmental factors must also be considered. There are two primary distinctions between XLPE cables and other types of cables that allow you to identify these sorts of cables; however, other functional qualities, such as resistance to heat up to 90 degrees, may also indicate that the cable in question is of the XLPE variety. 
These two purposes are as follows: The adaptability of the cable's insulating sheathing on the inside; In contrast to PVC cables, which are generally black in color, XLPE cables typically come in shades of white and gray, and occasionally black as well. When should XLPE cables be used, and why should they be utilized? Under the following circumstances, XLPE cables may be utilized in industrial settings:
- circumstances of temperatures that are either excessively cold or exceedingly hot;
- Electrical applications requiring high voltage;
- subject to the wear and tear caused by mechanical tension;
- areas that are wet or submerged;
- locations that are exposed to various contaminants.
The following are some of the benefits that XLPE cables offer:
- Because of the qualities of XLPE, it has a higher resistance to heat, reaching up to 90 degrees Celsius;
- Because of the cable's cross-linked polyethylene structure, flexibility and the capacity to alter its shape are inherent properties;
- Resistant to solvents and able to preserve its original electrical characteristics even when exposed to chemicals;
- Has the ability to tolerate temperature spikes of up to 250 degrees Celsius for a limited amount of time;
- In addition, this kind of cable has a strong resistance to both moisture and mechanical stress, as well as to the effects of sunshine.
In the following content we gathered some of the specific advantages of 66KV cable: High Continuous Current Rating: The conductor's higher continuous operating temperature of 90-C enables XLPE cables to carry higher amperage than PVC or paper insulated cables. 
Small deformation at high temperature: Under the combination of thermal and mechanical pressure, XLPE has a small deformation compared to other solid dielectrics. High short circuit value: XLPE insulated cables have a maximum allowable continuous temperature of 250-C during a short circuit, which greatly increases the short circuit value of XLPE cables compared to PVC and paper insulated cables. Low Dielectric Loss: The dielectric loss of XLPE is much lower than traditional solid dielectrics such as PVC and EPR. This is a huge cost saving when higher voltage power transmission is done over XLPE cables. High emergency overload capacity: XLPE cables can operate up to 130 C in emergency situations. This should not exceed 100 hours in a continuous 12-month period and 500 hours in the lifetime of the cable. Low charging current: The charging current is much lower than other dielectrics. This enables the closing set of the protection relay. High resistance to thermal deformation and aging in hot air provides an important advantage in cable ratings and is of particular interest in locations where ambient temperatures are high. These together with better stress crack resistance and low dielectric constant make XLPE cables particularly suitable for high and extra high voltage applications.
