Nyy cable is one of the many models of cables. Many people may not have heard of this cable when they don't know much about cables. Below zms cable team will take you through the meaning of NYY cable.
NYY power cables are an example of the German VDE standard.
Among them, NYY-O is equivalent to VV-0.6/1KV PVC insulated and sheathed power cable in the national standard GB12706. NYY-J is equivalent to KVV PVC insulated and sheathed control cable in the national standard GB9330.
Then you may wonder what is the meaning of NYY.
It belongs to one of the cable model names.
The so-called cable model refers to the cable classification, electrical equipment with wire and cable, and power cable models.
Cable model by the product series code and cable structure of each part of the code.
For example:
The full name of the model YJV22 cable is copper or aluminum core cross-linked polyethylene insulation.
The full name of the ZR-VV42 cable is PVC-insulated thick steel wire armored sheath flame retardant power cable.
The structure of NYy wire and cable mainly includes three parts:
Conductor: Standard copper core conductor, including single-core, multi-core, or stranded wire as required.
Insulation: Polyvinyl Chloride (PVC) is primarily used as an insulating material to protect the conductor and avoid short-circuiting the wire or cable.
Sheath: PVC or polyurethane (PUR) is usually used as the sheath material to protect the insulation from mechanical damage and chemical contamination.
NYY power cables are specialized in cable ducts, power stations, industrial and distribution boards, as well as in the supply of energy to the customer's network. It can also be used in brick walls, concrete, or non-compacted concrete.
Exceptions are made for present conditions that require chattering and swaying.
NYY cables can be installed in the open air, underground, underwater, and indoors in areas protected from mechanical damage.
This cable is UV-resistant and can be used outdoors.
The NYY cable range includes NYY-J and NYY-O cables.
These are widely used European power and control cables designed for fixed wiring installations and rated at 600/1000V.
Category J: Yellowish green (1/2), brown, black, gray
Category O: Blue (1/2), Brown, Black, Gray
- Solid or multi-stranded bare copper conductors
- According to DIN VDE 0295 cl.1/cl.2, BS 6360 cl.1/cl.2, IEC 60228 cl.1/cl.2
- PVC insulation category DIV4 according to HD 603.1
- Color coding according to DIN VDE 0293-308, 0276- 603/HD 186
- Core color for 3+1/2 conductors
- PVC sheath DMV category 5 according to HD 603.1
NYY cables can be safely deployed as power cables in most applications without mechanical stress.
For example indoors, outdoors, directly buried in the ground, in concrete, or submerged in water.
Where NYY cables need to be buried underground by the UK Wiring Regulations BS7671, they must be installed in conduits or pipes to prevent mechanical damage.
They are not suitable for installation in shaking, vibrating, or compressed concrete.
NYY-O construction differs from NYY-J in that it does not have a green or yellow ground wire.
These black NYY cables have a UV-stabilized outer jacket, making them suitable for direct exposure to sunlight.
They have an operating temperature range of -15oC to +70oC when fixed and -5oC to +50oC when bent.
1 Compact, easy to install and maintain.
2 Reliable conductor with good electrical properties.
3 Good insulation, resistant to electrical impregnation, heat, cold, and chemical corrosion, not easy to aging.
4 Good jacket, good resistance to mechanical damage, corrosion, and scorching.
5 Standard standardization, in line with domestic and international standards, is easy to select.
