He control cable 600V is an essential component in industrial electrical systems, automation, Motor control centers and energy generation plants. Your versatility, Durability and resistance to adverse environments make it the ideal choice for the transport of low voltage signals and electrical commands.
In this exhaustive guide, We will explore its structure, types of isolation (as XLPE y PVC), driver settings from 1 until 144 cores, protection with Steel wire armored (SWA) and its essential technical parameters.
What is a 600V control cable?
And control cable It is a low voltage energy cable designed to transmit electrical signals of control or information in industrial applications, commercial or automation. It is composed of several copper or aluminum conductors, Insulated individually and covered by protective layers against mechanical impacts, humidity, electrical interference and chemicals.
Typical 600V control cable applications
- Motor control centers (MCC)
- Industrial Automation Systems
- Electrical stations and substations
- HVAC Systems
- Petrochemical and miners plants
- Railways and infrastructure works
- Video surveillance cameras and sensors
Typical 600V control cable structure
Modern control cables can have different insulation combinations, armor and number of nuclei. The most common structure is the following:
- Conductor: Braided naked copper or tinned copper
- Isolation: XLPE (cross-linked polyethylene) o PVC (polyvinyl chloride)
- Filling and separation tape
- inner cover: PVC O LSZH (Low smoke emission and without halogen)
- Armor: Galvanized steel wire (SWA) or steel tape (STA)
- External cover: UV -resistant PVC, oils and abrasion
Types of isolation: XLPE vs PVC
XLPE (Crosslinked Polyethylene)
- Greater thermal resistance (up to 90 ° C in continuous operation)
- Excellent chemical resistance
- Less dielectric loss
- More structural rigidity
PVC (Polyvinyl chloride)
- Lower cost
- Flexible and easy to install
- Good fire resistance
- Suitable for interior facilities
Both types of isolation can be combined according to application: For example, XLPE insulation with PVC cover.
Common nuclei configurations: From 1 until 144
Control cables can have from 1 only nucleus to 144 cores, depending on the complexity of the control system and the amount of signals that must be transmitted.
| Common nuclei | Typical application |
|---|---|
| 1-4 cores | Simple signage, switches, sensors |
| 5-12 cores | Control panels, HVAC Systems |
| 14-24 cores | Machinery automation |
| 27-48 cores | Complex control systems |
| 50-144 cores | Advanced Command Centers, Electrical substations |
Armored control cable: Additional mechanical protection
He Steel wire armored control cable (SWA) It is a recommended option for demanding environments such as mines, chemical plants, Tunnels or underground facilities. This armor provides:
- High resistance to crushing
- Protection against rodents
- Accidental impact security
- Direct burial capacity
