Cabos Isolados de Alta Tensão
Indulink high-voltage cable is a type of power cable that is used to transmit electrical energy in high-voltage systems, with a nominal voltage rating of 69 kV. It is designed to be used in underground or overhead applications and is made up of copper or aluminum conductors coated with a cross-linked polyethylene (XLPE) insulator. The cable is protected by a high-density polyethylene (HDPE) outer jacket to resist mechanical damage and weathering. Indulink cable is known for its durability and resistance to high temperatures, making it a popular choice for electrical power transmission in high-voltage systems.
Applications
INDULINK 69 Kv ~138 kV CABLES are applicable to all public, industrial and utility environments (power generation, transmission and distribution). The cables can be installed in galleries, ducts, directly
buried or in sub-fluvial and sublacustrine crossings.
The sizing of high-voltage cables depends on the power to be transmitted, the applicable protections, the environmental and installation conditions (trefoil or apartment formation, natural or forced ventilation, etc.).
Construction
1. Conductor: Bare electrolytic copper or aluminum, soft temper, compacted circular stranded (Class 2), blocked against longitudinal water penetration.
2.Conductor shield: Semiconductor thermosetting compound.
3. Insulation: TR XLPE (Tree Retardant) 90° C cross-linked polyethylene thermosetting compound.
4. Insulation shielding: Semiconductor thermosetting compound.
5. Insulation wrapping: Semiconductor tape blocked against longitudinal water penetration.
6. Metal shield: Bare copper wire with a cross-section suitable for the project and blocked against longitudinal water penetration.
7.Separator: Semiconductor tape blocked against longitudinal water penetration.
8.Blocking: Polythene aluminum tape (APL) against radial water penetration.
9.Cover: Thermoplastic polyethylene compound PE ST7 (HDPE)
