8. Installation Precautions & Guidelines
Proper installation practices are essential for achieving optimal cable performance and maximizing service life. The following guidelines address critical considerations for VERSOLEX® 90OC cable installation.
Pre-Installation Requirements
Temperature Considerations: Installation should be performed when ambient temperature is within the specified range (-20°C to +60°C). In cold weather conditions below 0°C, cables may require pre-warming or conditioning before handling to prevent insulation cracking. Store cable drums in temperature-controlled environments when possible.
Installation Best Practices
Bend Radius Compliance
Never exceed minimum bending radius specifications. Use appropriate cable guides, sheaves, and support systems sized for cable diameter.
Pulling Tension Limits
Maximum pulling tension should not exceed conductor tensile strength limits. Use swivel pulling eyes to prevent torsional stress.
Support & Securing
Provide adequate support at regular intervals. Avoid point loading and ensure cable weight is distributed across support systems.
Termination Quality
Use appropriate lugs and connectors rated for conductor size. Ensure proper crimping or mechanical connection per manufacturer specifications.
Environmental Considerations
| Environment | Precaution Required | Recommended Action |
|---|---|---|
| High UV Exposure | Potential sheath degradation | Use UV-rated variants or protective conduit |
| Chemical Exposure | Verify compatibility | Consult chemical resistance charts; consider additional protection |
| High Humidity/Submersion | Moisture ingress at terminations | Use sealed glands and waterproof connectors |
| Mechanical Hazard Areas | Physical damage risk | Install protective covers, conduit, or cable trays |
| High Temperature Zones | Derating required | Apply derating factors per AS/NZS 3008.1 |
⛔ Safety Warning: Always de-energize circuits before performing installation or maintenance work. Verify isolation using appropriate test equipment. Follow all applicable electrical safety codes and workplace safety regulations. Only qualified electrical personnel should install, maintain, or terminate power cables.

9. Frequently Asked Questions
X-90 refers to cross-linked polyethylene (XLPE) insulation rated for 90°C continuous operation, while V-90 refers to PVC insulation with the same temperature rating. XLPE (X-90) offers superior thermal stability, lower dielectric losses, higher short-circuit temperature tolerance (250°C vs. 160°C), and better resistance to thermal deformation. XLPE is preferred for high-performance applications, while PVC offers cost advantages for less demanding installations.
While the TPE-90 sheath provides excellent moisture resistance, direct burial is generally not recommended for unarmoured flexible cables without additional mechanical protection. For direct burial applications, use protective conduit or specify armoured cable variants. The cable is suitable for installation in cable ducts and underground conduit systems where mechanical protection is provided.
Conductor size selection should be based on AS/NZS 3008.1 (Electrical installations – Selection of cables), considering factors including: maximum current demand, installation method, ambient temperature, grouping with other cables, and voltage drop requirements. For welding applications, reference AS/NZS 1995 duty cycle tables to match conductor size with anticipated operational duty cycle (100%, 60%, 35%, or 20%).
Under normal operating conditions (within specified temperature, voltage, and mechanical parameters), XLPE-insulated cables typically achieve 30+ years service life in fixed installations. For dynamic/reeling applications, service life depends on flexing cycles, operating conditions, and maintenance practices. Regular inspection and replacement scheduling based on observed wear is recommended for critical applications.
For VFD applications, additional considerations apply due to voltage spikes and harmonic content. While VERSOLEX® 90OC provides adequate insulation for standard VFD installations, screened/shielded variants may be required to minimize electromagnetic interference and bearing currents. Consult VFD manufacturer recommendations and consider symmetrical cable configurations for motor connections.
Standard sheath colour is orange for high visibility in industrial environments. Active conductors in multicore variants follow AS/NZS 3000 colour coding requirements. Custom colours may be available for specific applications subject to minimum order quantities. Contact technical sales for colour availability and lead times.
