The ZECA 4106/314 reel (Static Discharge/Grounding/Bonding Reel) is a specialized device designed for the effective extension and automatic retraction of a grounding cable in industrial environments with elevated electrostatic risk. Equipped with a durable and flexible PVC cable with a cross-section of 1x6 mm² and a length of 52 feet, it enables efficient discharge of static electricity from vehicles, tankers, containers, and other equipment—greatly enhancing safety in areas with explosion or fire hazards.

The robust housing made from technopolymer ensures resistance to mechanical damage, corrosion, and chemical exposure. With two operating modes—ratchet and continuous, the reel can be easily adapted to specific applications. The unit features strong steel clamp jaws, a galvanized steel return spring, and a durable mounting bracket, making it a reliable tool for industries such as manufacturing, transportation, and logistics.

Technical Specifications:

• Cable length: 52ft

• Cable type: H05 V-F, PVC, 500V insulation

• Cable cross-section: 1 x 8/32" (6 mm²)

• Cable diameter: 7/32" (5.5 mm)

• Collector insulation voltage: 2.5 kV

• Collector capacity: 20 A

• Protection rating: IP42

• Operating temperature: -5°C to +50°C

• Cable type: Highly flexible PVC

• Housing material: Technopolymer

• Return spring: Galvanized steel

• Clamp jaws: Galvanized steel

The reel offers two operating modes:

Ratchet Mode 7A

Allows the cable to be locked at a selected length for precise and safe grounding setup. The ratchet mechanism activates every 50 cm with an audible “click.” This mode is recommended when working with pneumatic or electric tools where a stable cable position is necessary.

Continuous Mode 7B

The ratchet lock is deactivated, enabling smooth extension and automatic retraction of the cable without stops. Ideal for dynamic applications such as use with winches, overhead cranes, or lifting systems. After use, the cable should be retracted carefully—do not let it snap back to avoid injury.

⚠️ Grounding reels are delivered with the cable stop device (mode 7) enabled.

Applications of Grounding Reels:

Warehouses

Used where electrostatic discharge protection is required during the transfer of flammable materials. The grounding reel ensures continuous grounding throughout the logistics process and is essential for meeting workplace safety standards in hazardous zones.

Refineries and Chemical Industry

Prevents sparking and electrostatic discharge during the transfer of flammable liquids. Its durable, chemical-resistant construction ensures long service life. Improves safety and ease of use in EX-rated zones.

Tanker Transport and Marine Industry

Provides effective grounding for fuel tankers, chemical containers, and tanks transported by sea. The reel performs reliably even in harsh weather conditions. Enables quick connection and safe disconnection of the grounding cable.

Use Cases for Grounding Reels:

• Electrical Industry: In manufacturing plants, power stations, and substations, grounding reels are used for grounding machinery and safely discharging static electricity.

• Chemical Industry: Grounding of tanks, pipes, and pumps in areas with electrostatic hazards during chemical processes.

• Electronics Laboratories: Protect sensitive equipment by safely discharging static.

• Industrial Facilities: Prevent static discharge during production and packaging processes (e.g., dairies, breweries, food processing plants).

• Chemical Labs: Safe grounding during manipulation of volatile substances.

• Transportation & Refineries: Ground tankers, fuel lines, and equipment to prevent sparks and explosions.

• Research Labs: Ground workstations and electronic devices in precision environments.

• Military Facilities: Ground communications equipment, generators, and other devices where electrical safety is critical.

Grounding reels also known as bonding reels or static discharge reels are a key component in ensuring electrical safety in environments where there is a risk of electrostatic discharge. Their use helps minimize the risk of electric shock, damage to electrical equipment, and potential hazards to personnel.
