Огнестойкость (Fire Resistance): The cable meets the IEC 60332-1-2 standard, ensuring it can withstand fire exposure and maintain its integrity, which is critical for safety in mining operations.
Маслостойкость (Oil Resistance): Compliant with EN 60811-404 and IEC 60811-404, this cable is resistant to oil, making it suitable for environments where oil exposure is common.
Климатическая стойкость (Climate Resistance): The cable can be used both indoors and outdoors, withstanding ozone and moisture exposure, ensuring its performance in varied climatic conditions.
Cable Construction
The construction of the NSSHCGEOEU 1kV cable is designed to maximize its durability and flexibility:
Проводник (Conductor): Made from flexible, tinned, multi-stranded copper wire with fine twisting (class FS), providing excellent conductivity and flexibility.
Заземляющая жила (Grounding Conductor): The cable includes sets of control and monitoring conductors arranged concentrically, enhancing safety.
Изоляция (Insulation): The insulation is made from PROTOLON, based on ethylene-propylene rubber, type compound 3GI3, which ensures excellent electrical insulation properties.
Маркировка жил (Conductor Marking): Main conductors are colored black, gray, and brown, while auxiliary conductors are blue, simplifying installation and maintenance.
Внутренняя оболочка (Inner Sheath): Made from vulcanized rubber based on ethylene-propylene rubber, type GM1B, providing additional protection.
Броня (Armour): The cable features a braid of steel and copper wires vulcanized between the inner and outer sheaths, adding mechanical strength.
Внешняя оболочка (Outer Sheath): The outer sheath is made from PROTOFIRM, based on polychloroprene, type 5GM5, and is yellow in color for visibility and additional durability.
Temperature Specifications
Understanding the temperature specifications is crucial for ensuring the cable's performance in various conditions:
Максимальная рабочая температура жилы (Maximum Operating Temperature): The cable can operate continuously at up to 90°C.
Температура короткого замыкания (Short Circuit Temperature): It can withstand temperatures up to 250°C during short circuits.
Минимальная температура окружающей среды для прокладки (Minimum Ambient Temperature for Installation): -40°C.
Максимальная температура окружающей среды для прокладки (Maximum Ambient Temperature for Installation): 80°C.
Температурный режим при подвижной инсталляции (Temperature Range for Mobile Installation): -20°C to 60°C.
Application Scenarios
Mining Operations: This cable is essential for mining operations where shearers and heading machines need a reliable connection to the power grid.
Its flexibility and durability ensure it can handle the stresses of constant movement.
Outdoor and Indoor Use: The cable’s resistance to climate, ozone, and moisture makes it versatile for both outdoor and indoor applications, ensuring consistent performance regardless of environmental conditions.
High-Stress Environments: With its robust construction, the cable can endure significant mechanical stresses, making it suitable for high-stress environments like mining, where equipment is in constant motion.
RFQ: Common Questions and Answers
What makes this cable fire-resistant?
The fire resistance (огнестойкость) is achieved through the use of materials and construction methods that meet the IEC 60332-1-2 standard. This ensures that the cable can maintain its integrity and performance even when exposed to fire.
How does the cable resist oil exposure?
The oil resistance (маслостойкость) is ensured by complying with EN 60811-404 and IEC 60811-404 standards. This means the materials used in the cable’s construction are chosen for their ability to resist degradation when exposed to oils.
Can this cable be used in extreme temperatures?
Yes, the NSSHCGEOEU 1kV cable is designed to operate in a wide temperature range. It can handle ambient temperatures from -40°C to 80°C during installation and from -20°C to 60°C during operation, making it suitable for various extreme conditions.
What makes the outer sheath durable?
The outer sheath (внешняя оболочка) is made from PROTOFIRM, based on polychloroprene, which is a type of rubber known for its durability and resistance to environmental factors. This ensures the cable remains intact and functional even in harsh conditions.
By understanding these key features and benefits, mining professionals can make informed decisions about the Волочильный Кабель Для Угольного Комбайна Type NSSHCGEOEU 1kV, ensuring they select the right cable for their specific needs, thus enhancing operational efficiency and safety.
