Description

The KPSSPEP-ng(A)-HF (KMSPEP-ng(A)-HF) is a shielded symmetrical twisted-pair installation cable manufactured by ENTE LLC — a Russian cable plant based in Oryol specializing in fire-resistant and halogen-free cable products. Designed for single stationary installation in fire and burglar alarm systems, access control systems, and industrial automation (SCADA/DCS) networks, the cable is rated for a working voltage of 300 V and produced under TU 27.32.13-018-37395223-2021.

The cable combines soft single-wire copper conductors with halogen-free polymer insulation, twisted into pairs and wrapped with a mica-containing thermal barrier (20% overlap) that preserves circuit integrity during fire exposure. An aluminum foil shield, applied longitudinally with a minimum 10% edge overlap, is paired with a tinned copper drain wire for reliable EMI attenuation.

The halogen-free red outer sheath completes the construction, allowing quick visual identification in alarm system installations.

Available in conductor cross-sections from 0.20 to 2.50 mm² and in single-pair through 12-pair configurations, the cable carries fire safety class P1b.8.1.2.1 per GOST 31565-2012. It is also approved for use outside hermetically sealed zones in nuclear power plant safety systems of Class 3 under OPB 88/97 (PNAE G-01-011), and is certified for both domestic supply and export to tropical climate regions.

Details & Equipment

Cable Cross-Section Views

Single-Pair Configuration (1×2)

Cross-sectional view of the 1×2 cable variant, showing the single twisted pair of halogen-free insulated copper conductors wrapped in the mica thermal barrier, enclosed by the aluminum foil shield with drain wire and the distinctive red halogen-free outer sheath.

Multi-Pair Configuration (2×2)

Cross-sectional view of the 2×2 variant, illustrating how individual twisted pairs are assembled into a common core before the mica barrier, aluminum foil screen, and red outer sheath are applied over the entire assembly.

Features

🔥

Fire Safety Class P1b

Classified P1b.8.1.2.1 per GOST 31565-2012, meeting the most stringent Russian requirements for cables installed in fire and security alarm systems.

🛡️

Mica Thermal Barrier

A mica-containing tape is wrapped around the core with 20% overlap before the outer sheath is applied, extending the cable's circuit integrity under direct fire conditions.

📡

Aluminum Foil + Drain Wire Shield

A longitudinally applied laminated aluminum foil shield (≥10% edge overlap) combined with a tinned copper drain wire ensures stable signal transmission in electromagnetically noisy environments.

☢️

Nuclear Power Plant Rated

Approved for use outside hermetically sealed zones in nuclear power plant safety Class 3 systems per OPB 88/97 (PNAE G-01-011), suitable for the most demanding regulated environments.

🌿

Halogen-Free Construction

Both the conductor insulation and outer sheath are made of halogen-free polymer compound, minimizing toxic and corrosive gas emission in the event of fire.

⚡

Precise Electrical Parameters

Circuit resistance per 1 km at 20 °C reaches as low as 16.0 Ω for 2.50 mm² conductors; insulation resistance is at least 100 MΩ/km, and attenuation at 1000 Hz does not exceed 2.50 dB/km for single-pair configurations.

Buyer Benefits

Halogen-free insulation and sheath dramatically reduce toxic gas and smoke density in fire conditions, protecting evacuation routes and sensitive equipment
Mica thermal barrier provides circuit survival beyond what standard halogen-free construction alone can offer, critical for fire alarm signal continuity
Aluminum foil screen with tinned copper drain wire suppresses electromagnetic interference, ensuring reliable data transmission in industrial settings
Fire safety class P1b.8.1.2.1 per GOST 31565-2012 satisfies strict Russian regulatory and project specification requirements for building safety systems
Nuclear-grade approval (OPB 88/97 Class 3) opens access to the most demanding regulated installations, including power generation facilities
Wide range of conductor cross-sections (0.20–2.50 mm²) and pair counts (1–12 pairs) allows a single cable series to cover diverse project wiring needs
Red outer sheath enables rapid visual identification of alarm system circuits during installation, commissioning and maintenance

Applications

Fire and burglar alarm systems (OPS) in commercial, industrial and public buildings Access control and physical security systems SCADA and DCS industrial process automation wiring Building management system (BMS) communication and control networks Nuclear power plant monitoring and signaling circuits (safety class 3, OPB 88/97) Telecom and data transmission networks requiring shielded twisted-pair cabling Export installations in tropical climate regions Single stationary wiring in systems subject to strict fire safety certification requirements
