45° ENTRY
ZERO COMPROMISE
Engineered To Withstand What We'll Never See
Inside the sealing system protecting Dunedin's most critical hospital build — one 45° penetration at a time.
Below the basement floor of the new Dunedin Hospital Inpatient Building, Hauff-Technik HSI sleeves and press seals are holding the line against water ingress at every service penetration. Specified by the project architects and supplied by TransNet, the system handles angled duct entries, cast-in wall sleeves, and multi-configuration seals — engineering that has to be right the first time.

Beneath Dunedin’s Most Critical Build Lies the Real Defence System
Following a long process working with the project architects in Christchurch and Dunedin, the design for the new Dunedin Hospital Inpatient Building specified the use of Hauff-Technik penetration sleeves and press seals for all below-ground service penetrations.
The foundation works are well under way. The basement floor design called for raised concrete service plinths to house the various types of ducts entering from underground at 45-degree angles.
Hauff-Technik slanted HSI sleeves were selected by the architect and supplied by TransNet to solve this challenge.
The second-stage top section of the service plinth was then cast around the HSI sleeve assemblies in the required orientations.
The final installation of the Hauff-Technik press seals, to seal around the ducts inside the HSI sleeves, will be completed by the services contractors at the next stage. In addition to the basement floor penetrations, there are also various types of wall penetrations incorporating cast-in wall sleeves and seals in multiple configurations.

Key Features
✓ Compact & Insulated Design – Made of highly modified, non-flammable silicone rubber that is heavily resistant to tracking
✓ Permanently Bonded Outer Screen – Features a permanently bonded thin-walled conductive screen that protects the system against accidental contact and ensures user safety
✓ Multi-application Use – Can be used on MV networks up to 42kV CAT No. : RSTI-68RC
used in medium voltage (typically 11kV to 33kV) electrical systems to safely cover, seal and earth an unoccupied Type-C equipment bushing
They are primarily used in switchgear, transformers and motors to provide the following functions:
✓ Environmental Protection – Seals the exposed bushing to prevent moisture, dust and debris ingress
✓ Insulation & Safety – Provides a fully insulated, dead-end termination
✓ Grounding – Typically supplied with an integrated earth lead to maintain proper system grounding.
MV Type-C dead-end receptacles (commonly used on 630A or 1250A bushings) require careful testing to ensure the integrity of the insulation, separable connections and the attached power cables. Testing generally includes AC or VLF Withstand, Partial Discharge (PD) Measurement and Tan Delta testing.
✓ Weather & Environmentally Sealed – Designed to prevent moisture ingress and safeguard the exposed, unused connections on dead-break systems
✓ Cable Compatibility – Fully compatible with interface type “C” bushings (630A / 1250A) in accordance with EN 50180/50181
Benefits
✓ Enhanced Safety – The grounded conductive outer screen ensures the touch-safe, “deadfront” integrity of the connection system, preventing accidental shock
✓ Equipment Protection – Protects, insulates and seals the bushings against dust, water and environmental contaminants
✓ Long Service Life – The high performance silicone rubber offers excellent elongation at break, high tracking resistance and unlimited shelf life
✓ Ease of Use – Fits effortlessly onto the rear of the connector to terminate an open circuit, requiring very few accessories for system testing and earthing
✓ Testing - Tested for AC withstand and Partial Discharge prior to leaving the factory
– AC Withstand Voltage: 94kV/1min
– Partial Discharge: 10pC @ 36kV
