Fire-resistant telecommunication cable HTKSHekw 2x2x1.0 TN0307

Fire-resistant telecommunication cable – safety and reliability of installation

HTKSHekw 2x2x1.0 cable is an advanced solution for installations requiring a high level of fire safety. Designed for use in alarm systems, emergency lighting, teletransmission systems, and fire alarm systems, it ensures continuous operation even in extreme conditions. The cable's construction, with a screen and halogen-free coating, minimizes the risk of fire spreading and the emission of toxic substances during a fire.

Construction and properties

The cable is characterized by copper conductors of class 1 (according to EN 60228 and IEC 60228) with a cross-section of 1 mm². Four cores provide flexibility in installation design. A static screen (ekw) effectively protects against electromagnetic interference. The use of halogen-free materials guarantees the absence of corrosive gas emissions during combustion, which is crucial for protecting health and equipment. Additionally, the cable meets stringent fire resistance standards – FE180 (insulation durability for 3 hours) and PH90 (function maintenance for at least 90 minutes).

Applications and compliance with standards

The HTKSHekw 2x2x1.0 cable is ideal for indoor installations where high fire resistance and the absence of toxic gases are required. It is particularly recommended for:

• Alarm and signaling systems
• Emergency lighting
• Teletransmission systems
• DSO systems (voice warning systems)
• Fire alarm and fire automation systems
• Other safety circuits

The cable has been tested according to DIN 4102 part 12 and can be used in cable routes E90 as part of a cable assembly E90 when mounted on holders every 30 or 60 cm. It has a CNBOP certificate.

Operating parameters

The cable is intended for permanent installation in rooms protected by sprinklers. It can be laid at a temperature of -5°C, and the operating temperature ranges from -25°C to +70°C. Insulation resistance is minimum 500 MΩ/km, and capacitance is 150 nF/km. Rated voltage is 1500 V AC / 2250 V DC.
