Trafficable Cable Pits and Underground Power Systems

Trafficable Cable Pits and Underground Power Systems

Weber South Pacific’s trafficable cable pits are suitable for a wide range of applications from the smallest cable access point to large HV pits and culverts under padmounted transformers. Sizes range from 250×250 to 4400×2200 (mm) with depths varying up to 3000mm.

Pits are manufactured using 100% recycled modified polycarbonate. They can be delivered to site complete or in pieces for ease of handling. Where site access for heavy lifting equipment is difficult on site assembly can carried out by two people. Lid options using composites rather than cast iron assists this process.

Installation of a trafficable cable pit

The modular system includes a wide range of sizes for trafficable applications similar to class E to AS3996. While this standard sets the criteria for pit lids only, Weber’s partner Langmatz has had the pit range tested to ensure it is fit for purpose without further bracing or reinforcement.

The German civil engineering organisation DiBT has independently confirmed the suitability of these products for trafficable applications.


A wide range of lid locking options is available. These range from the standard D bolt to customer specific designs for additional security.

The wide range of applications serviced by the product range are:

  • Culverts for padmounted transformers and HV switching stations up to a load weight of 40t
  • Cable access points with draw in pulley facilities
  • Housing in-ground / underground low-voltage switchgear
  • Cable pits to fit over existing conduits
  • Mounting point for street cabinets (traffic lights, low voltage distribution pillars ect) to provide good cable access
  • Telecommunications pits for optical fibre equipment
  • Housing electrical and telecommunications equipment inground in a dry environment
  • Housing power distribution in-ground / underground for temporary market sites
  • HV cable pits
  • Trafficable pits for housing water meaters
