KYJVP22 cable
The KYJVP22 cable stands as a high-performance industrial control and instrumentation cable engineered for environments demanding exceptional durability, signal integrity, and electromagnetic interference (EMI) protection. Its robust, multi-layer construction is specifically designed to ensure reliable data transmission and control signal accuracy in complex industrial settings, including power plants, manufacturing facilities, and automation systems. A key component of its superior design is the use of a tinned Copper Core XLPE Insulated PVC Sheathed Copper Wire Braided Shielded STA Control Cable. This foundational element provides excellent conductivity and corrosion resistance. The overall architecture of the KYJVP22 cable integrates cross-linked polyethylene (XLPE) insulation for thermal stability, a comprehensive copper wire braided shield for effective EMI/RFI rejection, and a sturdy PVC outer sheath, often augmented with a steel tape armor (indicated by '22'), offering supreme mechanical protection against crushing, abrasion, and rodent damage. This makes it an indispensable solution for fixed installations in harsh conditions where both electrical performance and physical resilience are non-negotiable.
When specifying cables for mission-critical applications, understanding the detailed parameters of the **KYJVP22 cable** is essential. Below is a comprehensive breakdown of its technical specifications and construction, presented to facilitate precise selection and integration into your systems.
**Core Construction & Electrical Properties:**
* **Conductor:** Plain annealed copper, stranded (Class 2 per IEC 60228).
* **Conductor Cross-Section:** Available from 0.75 mm² to 10 mm² (or equivalent AWG sizes).
* **Insulation:** Cross-Linked Polyethylene (XLPE). This material offers high-temperature resistance, excellent dielectric strength, and long-term aging stability.
* **Individual Shielding:** Each insulated core is typically wrapped with a polyester film and shielded with a tinned copper braid, ensuring individual pair isolation from interference.
* **Overall Shielding:** A high-density tinned copper wire braid is applied over the assembled cores, providing comprehensive collective shielding effectiveness.
* **Armoring:** Galvanized steel tape armor, applied longitudinally or helically, offers exceptional mechanical protection (crush resistance, rodent protection).
* **Outer Sheath:** Polyvinyl Chloride (PVC), resistant to oils, acids, alkalis, and sunlight, suitable for various industrial environments.
* **Nominal Voltage:** 300/500V.
* **Temperature Range:** -20°C to +70°C for fixed installation. The XLPE insulation allows for a maximum conductor temperature of 90°C during operation.
* **Standards Compliance:** Generally manufactured to meet or exceed standards such as GB/T 9330, IEC 60502, and other relevant international specifications.

| **Overall Shielding** | Tinned Copper Wire Braid |
| **Armor Type** | Galvanized Steel Tape (STA) |
| **Sheath Material** | Polyvinyl Chloride (PVC) |
| **Min. Bending Radius** | 12 x Overall Cable Diameter (Fixed Installation) |
| **Operating Temp. Range** | -20°C to +70°C (Max. Conductor Temp.: 90°C) |
| **Flame Retardancy** | IEC 60332-1 (Standard) optionally available: IEC 60332-3 Cat A |
**Applications:**
The **KYJVP22 cable** is ideally deployed in areas susceptible to electromagnetic interference and requiring robust physical protection. Its primary applications include:
* Connection of instrumentation and control equipment in power generation and distribution.
* Signal transmission for process automation in chemical and petrochemical plants.
* Control circuits in manufacturing and assembly lines.
* Building management systems (BMS) and supervisory control and data acquisition (SCADA) systems.
* Any fixed installation where cables are exposed to potential mechanical stress, moisture, or corrosive agents.
