What is a YJV Copper Core Cable?

What is a YJV Copper Core Cable

1. What is a Copper Core Cable?

A copper core cable refers to a cable with a conductor made of copper.

2. What is a 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 signify?

Introduction to YJV Cable

YJV: Copper core cross-linked polyethylene insulated PVC sheathed power cable

YJ: Cross-linked polyethylene insulation

V: PVC sheath

The YJV cable is composed of several parts from inside to outside: the conductor, polyethylene insulation, filler (like nylon, PVC composite materials, etc.), and a PVC outer sheath. The conductor is typically a copper core, as copper is a widely used conductor material in the market.

Aluminum conductors are less used due to their poor electrical conductivity and lack of standardization. Fillers are typically made from materials like nylon and serve to protect the core of the wire, akin to dressing the cable core in a “coat”.

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

  1. Applicable Scope

The cable is suitable for fixed installation on AC 50Hz power transmission and distribution lines with a rated voltage of 0.6/1kV and below for power transmission. Compared to PVC power cables, this product not only has excellent electrical performance, mechanical performance, heat aging resistance, environmental stress resistance, and chemical corrosion resistance but also features a simple structure, light weight, is not limited by laying drop, and has a high long-term working temperature (90℃).

  1. Implementation Standard

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. Commonly Used YJV Cable Specifications and Models

YJV cables can consist of either a single conductor or multiple conductors. The number of cores in a YJV cable can be single-core, 2-core, 3-core, 4-core, 5-core, 3+1-core, 3+2-core, 4+1-core, etc.

The 3+1-core, 3+2-core, 4+1-core models are composed of two conductors with different functions, one is called a phase line, and the other is a grounding line, specifically used for grounding.

Common specifications are 1mm², 1.5mm², 2.5mm², 4mm², 6mm², 10mm², 16mm², 25mm², 35mm², 50mm², 70mm², 95mm², 120mm², 150mm², 185mm², 240mm², 300mm², etc. For instance, the YJV3185+295 cable consists of three 185mm² phase lines and two 95mm² grounding lines.
