QHJ02: Definition and Properties

QHJ02, short for Quality-tested High Density Polyethylene Insulation Material, refers to a specific type of high-density polyethylene (HDPE) insulation material used in telecommunication cables. HDPE is a thermoplastic polymer with high strength, low moisture absorption, excellent electrical insulation properties, and resistance to chemicals and UV rays. The QHJ02 insulation material adheres to international standards, including ISO/IEC 11803-6, IEC 60502, and ASTM D795.

Properties of QHJ02:

1. Strength: QHJ02 exhibits exceptional strength due to its high molecular weight and crystallinity. It can withstand high tension and compression forces without degrading or breaking down.

2. Moisture Absorption: QHJ02 has a low water vapor transmission rate (WVTR), making it suitable for applications in harsh environments where moisture could cause damage. The WVTR of QHJ02 ranges from 0.02 to 0.07 per cent at 93°C and 10% relative humidity, respectively.

3. Electrical Insulation: QHJ02 provides excellent electrical insulation properties, ensuring minimal electrical interference between adjacent conductors. Its low smoke development rate (SDR) and low halogen content also contribute to better insulation performance.

4. Chemical Resistance: QHJ02 is highly resistant to chemicals and UV rays, making it suitable for use in cable installations exposed to environmental stressors. It can resist solvents, acids, and bases without degrading or breaking down.

Applications of QHJ02:

QHJ02 insulation material finds extensive use in various telecommunication cable applications, such as:

1. Power Cables: QHJ02 is commonly used in high-voltage power cable applications, providing excellent electrical insulation properties and durability. It is also flame retardant and can withstand temperatures up to 135°C for extended periods.

2. Data Transmission Cables: QHJ02 is suitable for data transmission cables used in local area networks (LANs) and wide area networks (WANs). It ensures minimal signal interference and supports fast data transfer rates.

3. Telecommunications Fiber Optic Cables: QHJ02 is widely used in fiber-optic cable insulation, providing high flexibility and resistance to mechanical stress. It also offers good optical transparency and low attenuation characteristics.

Benefits of QHJ02:

The advantages of using QHJ02 insulation material in telecommunication cable installation are numerous, including:

1. Improved Performance: QHJ02's superior electrical insulation properties help minimize electrical interference and ensure reliable data transmission rates. Additionally, its chemical resistance makes it more durable than other insulation materials commonly used in telecommunication applications.

2. Cost-Effectiveness: QHJ02 is a cost-effective solution compared to other insulation materials due to its high production efficiency and lower raw material costs. It also offers longer service life, reducing the need for frequent replacements and maintenance.

3. Safety: QHJ02 meets strict safety standards set by international organizations such as ISO International and the American Petroleum Institute (API). It is non-toxic, odorless, and free from harmful chemicals that could pose risks to users and the environment.

In conclusion, QHJ02, as a high-density polyethylene (HDPE) insulation material, plays a crucial role in ensuring reliable and efficient communication systems in telecommunication applications
