Introduction
KEI, as a leading high voltage cable manufacturer in India has a state of art high voltage cable plant that uses German technology and features a manufacturing capability of upto 220KV.High Voltage cables at KEI are manufactured as outlined with Indian Standard specification, IS: 7098 Part II, also our skilled research & development team can assist manufacturing as per International standard viz. IEC, BS, NFC, AS/NZS, VDE, SABS etc. & exporting to Overseas market.
Applications
KEI’s High Voltage Cables include voltage grade ranges in 3.3 kV to 33 kV, suitably ideal for power transmission & distrubution.
Features
KEI offers High Voltage Cables with following special features adopting the site installation requirements.
- Water/moisture resistant MV cables : Cables designs incorporating corrugated Aluminium sheath (CAS), corrugated Copper sheath (CCU), corrugated Stainless steel sheath (CSS), lead alloy sheath (LAS) or Polyethylene laminated Aluminium tape (APL) are most suitable cable designs to lay in conditions susceptible to water & moisture.
- Flame retardant (FR), Flame retardant low smoke & halogen (FR-LSH), low smoke, zero halogen (LSZH) MV cables : At stringent places like hospital, cinema halls, shopping malls, tunnels, Airports, intermittent or continuous presence of flamable gaseous materials etc., cables subjected to fire are constructed with the above material for full safety.
- Rodent & termite resistant MV cables : Cables are designed for robust protection needed to block rodents and polyamide jacket provides anti-termite protection.
Why Our HV Cables?
Our High Voltage cables are manufactured using latest in technology triple layer extrusion, with Semiconducting bonded conductor screen, XLPE or EPR insulation and over semiconducting layer in one continous process, ensuring longer cable lifespan with minimal breakdowns. XLPE use in cables ensures excellent Electrical and Mechanical performance, also with lower dielectric factor.
Introduction
Low Voltage Cables come in a variety of sizes, materials, and types, each particularly adapted to its uses. Cables consist of three major components: conductors, insulation, and protective outer sheath. The makeup of individual cables varies according to application.
The construction and material are determined by three main factors
- Working voltage, determining the thickness of the insulation
- Current-carrying capacity, determining the cross-sectional size of the conductor(s)
- Environmental conditions such as temperature, water, chemical or sunlight exposure, and mechanical impact, determining the form and composition of the outer sheath of cable.
LV cables use stranded copper or aluminum conductors. although small conductor of cables may use solid conductors. The overall assembly may be round or flat. Non-conducting filler strands may be added to the assembly to maintain its shape. Special purpose LV cables for overhead or vertical use may have additional elements such as steel structural supports. Some LV cables for outdoor overhead use may have no outer sheath.
