1. What is copper core cable?
A copper core cable refers to a cable with a conductor made of copper.
2. What is YJV copper core cable?
Cables can be categorized into various types and specifications according to different classification standards. Among them is the YJV cable. What exactly is a YJV cable and what are the specifications of this model? What does the YJV model mean?
YJV Cable Introduction
YJV: PVC sheathed power cable insulated with cross-linked polyethylene with copper core
YJ: Cross-linked polyethylene insulation
V: PVC sheath
YJV cable is composed of several parts from the inside to the outside: the conductor, polyethylene insulation, filler (such as nylon, PVC composite materials, etc.) and an outer PVC sheath. The conductor is normally a copper core, as copper is a widely used conductive material in the market.
Aluminum conductors are less used due to their low electrical conductivity and lack of standardization. Fillers are typically made from materials such as nylon and serve to protect the wire core, similar to dressing the cable core in a “jacket.”
Low Voltage: 0.6/1KV (available in single core, two cores, three cores, four cores, 4+1 cores)
Medium Voltage: 3.6/6KV, 6/10KV, 8.7/15KV, 12/20KV, 18/30KV, 26/35KV
- Applicable scope
The cable is suitable for fixed installation in 50 Hz AC power transmission and distribution lines with nominal voltage of 0.6/1 kV and below for power transmission. Compared to PVC power cables, this product not only has excellent electrical performance, mechanical performance, thermal aging resistance, environmental stress resistance and chemical corrosion resistance, but also features simple structure, light weight, is not limited by falling seating and has a high long-term working temperature (90 ℃).
- Implementation Pattern
Low voltage power cable products comply with the GB/T12706.1-2008 standard. Flame retardant or fire resistant cables must also comply with the GB/T19666-2005 standard.
3. Specifications and models of commonly used YJV cables
YJV cables can consist of a single conductor or multiple conductors. The number of cores in a YJV cable can be single core, 2 cores, 3 cores, 4 cores, 5 cores, 3+1 cores, 3+2 cores, 4+1 cores, etc.
The 3+1 cores, 3+2 cores, 4+1 cores models are composed of two conductors with different functions, one is called a phase line and the other is a grounding line, used specifically for grounding.
Common specifications are 1mm², 1.5mm², 2.5mm², 4mm², 6mm², 10mm², 16mm², 25mm², 35mm², 50mm², 70mm², 95mm², 120mm², 150mm², 185mm², 240mm², mm², etc. 185+2 Cable 95 consists of three 185 mm² phase lines and two 95 mm² ground lines.
