Wiring harnesses for elevator applications
The elevator wiring harness is a complex of multiple wires and connectors, which is mainly used to transmit power and signals to ensure that the elevator can work on time and as needed. It is a key component for the normal operation of the elevator, responsible for connecting the various components of the elevator and transmitting information such as operating status and load conditions to the control system.
Elevator wiring harnesses need to comply with relevant safety standards and regulatory requirements to ensure the safe operation of elevators. Elevator wiring harnesses need to have fire prevention, protection and anti-interference capabilities to prevent electrical failures and electromagnetic interference from affecting the elevator system. Before production, elevator wiring harnesses also need to consider factors such as high temperature resistance, and pass high and low temperature cycle, waterproof sealing and other tests to ensure stable operation under high temperature (withstand -40℃~150℃) and frequent vibration in the machine room.
The difference between elevator wiring harness and automobile wiring harness
| Contrast Dimensions | Elevator wiring harness | Automotive wiring harness |
| Core features | Transmit power and control signals, connect traction machine, door machine drive, floor display and other modules | Subsystems transmit power and signals (engine, body, lights, etc.), new energy vehicles include high-voltage wiring harnesses (300V+) |
| Material and protection | High-purity copper core + silicone casing, UL94-V0 flame retardant certification, resistant to extreme temperatures of -40℃~150℃ | Copper conductor + corrugated tube/tape protection, two-color wire identification system (single color preferred), oil and vibration resistant |
| Design Standards | Comply with elevator industry safety standards (fire prevention, anti-electromagnetic interference), and must pass high and low temperature cycle tests | Follow ISO/AWG wire specifications and strict terminal crimping process (cold pressing is better than welding) |
| Application scenarios | Traditional elevators (traction machines, door machines), smart elevators (integrated optical fiber/CAN bus) | Engine wiring harness, body wiring harness, new energy high-voltage wiring harness (drive power transmission) |
| Environmental adaptability | Resistant to high temperature and frequent vibration environment in the equipment room, protection level must meet IP67/IP69 | Adapt to -40℃~125℃ temperature range and oily and wading conditions (engine compartment wiring harness needs additional reinforcement) |
Summary of key differences
- Functional scalability: Elevator wiring harnesses focus more on signal stability and anti-interference capabilities, while automotive wiring harnesses need to be compatible with a variety of on-board devices (such as smart cockpits, BMS systems).
- Manufacturing process: Automotive wiring harnesses require higher terminal crimping accuracy (such as stripping length error must be ≤0.5mm), while elevator wiring harnesses emphasize modularity and long-term durability of wiring harness layout.
- Industry specifications: Automotive wiring harnesses must comply with national color codes (such as black for grounding wires), while elevator wiring harnesses must meet mechanical strength requirements under specific load scenarios.
As the "neural network" of the elevator system, the design and manufacturing of the elevator wiring harness must take into account safety, environmental adaptability and long-term durability. It is the core component to ensure the efficient operation of the elevator.
