RRU / BBU & Telecom Power Assemblies
Semita pre-terminated -48V DC telecom power cable assemblies deliver dependable electrical energy from base station rectifiers to tower-top Remote Radio Units (RRU). Featuring Class 5 high-flexibility stranded copper, flame-retardant XLPE insulation, and factory overmolded circular IP67 bayonet connectors, these assemblies eliminate on-tower termination errors.
Key Engineering Features
- Pre-terminated with factory overmolded circular waterproof bayonet or screw-lock connectors
- Class 5 high-flexibility stranded electrolytic annealed copper minimizes voltage drops
- Flame-retardant, UV-resistant cross-linked polyethylene (XLPE) dual-layer insulation
- Withstands harsh thermal extremes (-40°C to +90°C) on high mast installations
- 100% factory tested for electrical continuity, insulation resistance, and dielectric withstand

Shielded / Screened DC Power Cables
Semita shielded DC power cables feature an overall high-coverage tinned copper braid shield designed to prevent switching regulator electrical noise from coupling into adjacent sensitive RF antenna feeder lines on cellular towers and inside telecom shelters.
Key Engineering Features
- Dense ≥ 85% coverage tinned copper wire braid suppresses high-frequency electromagnetic noise
- Prevents DC power feed ripple from causing receiver desensitization in co-located RF lines
- Finely stranded Class 5 copper cores ensure easy routing around tight cabinet corners
- Low smoke zero halogen (LSZH) or UV-stabilized flame-retardant outer sheath
- Color-coded positive/negative conductors (Blue/Grey or Red/Black) for error-free polarity
