Extra-high Voltage Cables

As demand for power has been increasing and power transmission requires higher capacity, super-high voltage underground power cables are necessary to ensure reliability and safety of power transmission as well as a more pleasant urban appearance. XLPE insulation cables are becoming increasingly popular since they are easy to handle, can be easily connected and repaired, and have excellent electrical characteristics.

XLPE Insulation Cables

Polyethylene is the basic material of XLPE. The chemical structure of XLPE is converted into cross-linked XLPE through the use of organic peroxides. The cross linking method for polyethylene was developed in the U.S. in the 1950s and technologies for higher voltage continue to be developed. Growth aims at higher voltage and 500kV XLPE cables have already been commercialized.

Characteristics

Plastic insulation is becoming increasingly popular in advanced countries due to its superior insulation properties, simple installation and connectivity, and easy maintenance. In particular, XLPE insulation cables enable higher voltage capacity due to the growth of cross linking technologies. The 500 kV OF cables have quickly and completely been replaced with XLPE insulation cables. XLPE has advantages in weight, heat properties, and low installation and material costs.



Medium & Low Voltage Cable

This cable is made by wrapping the conductor with cross-linked polyethylene, which is an insulation material. This is a distribution cable rated for 0.6/1kV to 33kV.

What are Medium/Low Voltage Cable? 
The insulation material of this cable is cross-linked polyethylene, which has a heat-resistance rating up to 90℃. Thus this product is excellent for applications requiring intensive heat resistance. It is categorized as flame retardant, heat-resistant, or environmentally friendly depending on its features.

Uses
  • It is often used to supply power reliably to commercial or residential buildings and to industrial distribution circuits.
  • Also, places where high flame retardant performance is required to prevent catastrophic fires from being spread
  • Places where high flame retardant performance for public facilities such as hospitals, underground shopping centers, airport terminals, large buildings,?and subways is required and toxic gas and fumes from fire need to be suppressed.


Characteristics
  • Ensures excellent performance through self-development and reliable processing of cable materials based on the best technical competency and R D. These cables have the optimal exterior finish appropriate for the features.
  • Easy to make or connect due to its optical cable structure and configuration
  • New materials that do not contain substances harmful to environments are used for environmentally friendly cables.


Main Features
  • Regular: Used for interior wiring of housing and commercial buildings as well as industrial distribution circuits
  • Flame-retardant: Used for preventing fires (F-series)
  • Heat Resistance: Designed with firefighting in mind (F-FR-8)
  • Low Toxic, Lead-free: Environmentally friendly as it is made with materials that are not harmful to?the environment and does not emit toxic gases and noxious smoke in case of fire. (ZeLos)
  • Watertight: Used to prevent water tree from occurring at the insulator (FR-CN/CO-W
  • For External Use: Metal exterior to prevent insulating the cores
  • Chemical Resistance: Used in chemical factories that may be exposed to flamable gas fumes and that require chemical resistance


Cables for Control, Signals, and Instrumentation

Cross-linked polyethylene such as flame-retardant vinyl (PVC), which is heat-resistant up to 90℃, ensures excellent heat proofing since it is made of efficient insulation materials. These cables have a shielding feature appropriate for devices that require precision, are flame-retardant, and are environmentally friendly.

What are Cables for Control, Signals, and Instrumentation?
Cables are wrapped with insulation materials such as vinyl (PVC) or cross-linked polyethylene over conductors. These cables are used for signals and instrumentation that are supplied to control circuits of less than 0.6/1 kV as well as to precision devices.

Uses
  • Cables for Control
    Used for power supplied to the inside of buildings for housing and commercial use and to the circuits of industry control facilities
  • Cables for Signals and Instrumentation
    Used to transmit control signals between devices of industrial and security facilities and inside public and private buildings as well as to prevent external noise and interference between cores.

Characteristics
  • Ensures excellent performance through self-development and reliable processing of cable materials based on the best technical competency and R D. These cables have the optimal exterior finish appropriate for the application.
  • Prevents interference between cores, and shields external noise well. These features are required for precise, high-end control and signaling devices.


Main Features
  • Regular: Used for distribution circuits for industry and for the interior wiring of public and private buildings.
  • Flame-retardant: Used for preventing secondary fires (F-series)
  • Heat-proof: Used for firefighting (F-FR-3)
  • Low Toxicity, Lead Free: Environmentally friendly products whose materials are not harmful to the environment and that prevent the occurrence of toxic gas and noxious smoke in case of fire (ZeLos)
  • Shielding: Used to prevent interference between cores and to shield external noise (-I/CAMS)
  • For External Use: Metal exterior for preventing insulating cores


Insulation Cables 

Insulation cables ensure excellent heat-resistance by using halogen free,flame-retardant cross-linked polyolefin, heat-resistant to 90℃, and heat-resistant vinyl (PVC).

What are Insulation Cables?  
Insulation cables are wrapped with insulation materials that are lead-free, heat-resistant vinyl (PVC) or halogen free, flame-retardant cross-linked polyolefin over conductors. These cables are used for the cabling of electric devices of less than 450/750 V and for internal power supply.

Uses

Used for the cabling of electric devices such as devices for power supply to the interior of residential and commercial buildings or for regular electric facilities

Characteristics
  • Ensures excellent performance through a company-developed, reliable processing of cable materials based on the best technical competencies and R D. These cables have the optimal exterior finish appropriate for the application.
  • The heat-resistant vinyl (PVC) contains no lead. Environmentally friendly insulation cables raise heat-resistance capability to 90℃ due to the materials developed by LS to raise the allowable current.


Main Features
  • Heat-resisting Vinyl: Environmentally friendly, lead-free materials
  • Low-toxic, Flame-retardant: Environmentally friendly. Prevents toxic gas and noxious smoke from being generated in the event of a fire (ZeLos)

OPGW (Optical fiber overhead Ground Wire)

Optical fiber is added to the features of overhead power transmission lines. It protects power transmission lines from lightning strikes and power surges when power transmission lines fail, and also allows the addition of communication features. OPGW is currently used for many aerial lines.

Characteristics

OPGW is categorized as loose buffer-type OPGW made by containing optical fibers in a plastic tube and SSLT-type OPGW made by containing optical fiber in a stainless steel tube, depending on the structure of the optical fiber unit that wraps the optical fiber.
